description
The TLV277x CMOS operational amplifier family combines high slew rate and bandwidth, rail-to-rail output
swing, high output drive, and excellent dc-precision. The device provides 10.5 V/µs of slew rate and 5.1 MHz
of bandwidth while only consuming 1 mA of supply current per channel. This ac-performance is much higher
than current competitive CMOS amplifiers. The rail-to-rail output swing and high output drive make these
devices a good choice for driving the analog input or reference of analog-to-digital converters. These devices
also have low distortion while driving a 600-Ω load for use in telecom systems.
These amplifiers have a 360-µV input offset voltage, a 17 nV/√Hz input noise voltage, and a 2-pA input bias
current for measurement, medical, and industrial applications. The TLV277x family is also specified across an
extended temperature range (−40°C to 125°C), making it useful for automotive systems.
These devices operate from a 2.5-V to 5.5-V single supply voltage and are characterized at 2.7 V and 5 V. The
single-supply operation and low power consumption make these devices a good solution for portable
applications. The following table lists the packages available.

†Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltage values, except differential voltages, are with respect to GND.
2. Differential voltages are at the noninverting input with respect to the inverting input. Excessive current flows when input is brought
below GND − 0.3 V.
3. The output may be shorted to either supply. Temperature and/or supply voltages must be limited to ensure that the maximum
dissipation rating is not exceeded.

driving a capacitive load
When the amplifier is configured in this manner, capacitive loading directly on the output decreases the device’s
phase margin leading to high frequency ringing or oscillations. Therefore, for capacitive loads of greater than
10 pF, it is recommended that a resistor be placed in series (RNULL) with the output of the amplifier, as shown
in Figure 58. A minimum value of 20 Ω should work well for most applications.

When receiving low-level signals, limiting the bandwidth of the incoming signals into the system is often

If even more attenuation is needed, a multiple pole filter is required. The Sallen-Key filter can be used for this
task. For best results, the amplifier should have a bandwidth that is 8 to 10 times the filter frequency bandwidth.
Failure to do this can result in phase shift of the amplifier.

APPLICATION INFORMATION
using the TLV2772 as an accelerometer interface
The schematic, shown in Figure 62, shows the ACH04-08-05 interfaced to the TLV1544 10-bit analog-to-digital
converter (ADC).
The ACH04-08-05 is a shock sensor designed to convert mechanical acceleration into electrical signals. The
sensor contains three piezoelectric sensing elements oriented to simultaneously measure acceleration in three
orthogonal, linear axes (x, y, z). The operating frequency is 0.5 Hz to 5 kHz. The output is buffered with an
internal JFET and has a typical output voltage of 1.80 mV/g for the x and y axis and 1.35 mV/g for the z axis.
Amplification and frequency shaping of the shock sensor output is done by the TLV2772 rail-to-rail operational
amplifier. The TLV2772 is ideal for this application as it offers high input impedance, good slew rate, and
excellent dc precision. The rail-to-rail output swing and high output drive are perfect for driving the analog input
of the TLV1544 ADC.

The sensor signal must be amplified and frequency-shaped to provide a signal the ADC can properly convert
into the digital domain. Figure 62 shows the topology used in this application for one axis of the sensor. This
system is powered from a single 3-V supply. Configuring the TLV431 with a 2.2-kΩ resistor produces a reference
voltage of 1.23 V. This voltage is used to bias the operational amplifier and the internal JFETs in the shock
sensor.

APPLICATION INFORMATION
gain calculation
Since the TLV2772 is capable of rail-to-rail output using a 3-V supply, VO = 0 (min) to 3 V (max). With no signal
from the sensor, nominal VO = reference voltage = 1.23 V. Therefore, the maximum negative swing from nominal
is 0 V − 1.23 V = −1.23 V and the maximum positive swing is 3 V − 1.23 V = 1.77 V. By modeling the shock sensor
as a low impedance voltage source with output of 2.25 mV/g (max) in the x and y axis and 1.7 mV/g (max) in
the z axis, the gain of the circuit is calculated by equation 1.
Gain +Output Swing
Sensor Signal Acceleration (1)
To avoid saturation of the operational amplifier, the gain calculations are based on the maximum negative swing
of −1.23 V and the maximum sensor output of 2.25 mV/g (x and y axis) and 1.70 mV/g (z axis).

By selecting R3 = 10 kΩ and R4 = 100 kΩ, in the x and y channels, a gain of 11 is realized. By selecting
R3 = 7.5 kΩ and R4 = 100 kΩ, in the z channel, a gain of 14.3 is realized. The schematic shows the configuration
for either the x- or y-axis.
bandwidth calculation
To calculate the component values for the frequency shaping characteristics of the signal conditioning circuit,
1 Hz and 500 Hz are selected as the minimum required 3-dB bandwidth.
To minimize the value of the input capacitor (C1) required to set the lower cutoff frequency requires a large value
resistor for R2 is required. A 1-MΩ resistor is used in this example. To set the lower cutoff frequency, the required
capacitor value for C1 is:
C1 +1
2pfLOW R2+0.159 µF (4)
Using a value of 0.22 µF, a more common value of capacitor, the lower cutoff frequency is 0.724 Hz.
To minimize the phase shift in the feedback loop caused by the input capacitance of the TLV2772, it is best to
minimize the value of the feedback resistor R4. However, to reduce the required capacitance in the feedback
loop a large value for R4 is required. Therefore, a compromise for the value of R4 must be made. In this circuit,
a value of 100 kΩ has been selected. To set the upper cutoff frequency, the required capacitor value for C2 is:
C2 +1
2pfHIGH R4+3.18 µF (5)
Using a 2.2-nF capacitor, the upper cutoff frequency is 724 Hz.
R5 and C3 also cause the signal response to roll off. Therefore, it is beneficial to design this roll-off point to begin
at the upper cutoff frequency. Assuming a value of 1 kΩ for R5, the value for C3 is calculated to be
0.22 µF.

APPLICATION INFORMATION
circuit layout considerations
To achieve the levels of high performance of the TLV277x, follow proper printed-circuit board design techniques.
A general set of guidelines is given in the following.
DGround planes—It is highly recommended that a ground plane be used on the board to provide all
components with a low inductive ground connection. However, in the areas of the amplifier inputs and
output, the ground plane can be removed to minimize the stray capacitance.
DProper power supply decoupling—Use a 6.8-µF tantalum capacitor in parallel with a 0.1-µF ceramic
capacitor on each supply terminal. It may be possible to share the tantalum among several amplifiers
depending on the application, but a 0.1-µF ceramic capacitor should always be used on the supply terminal
of every amplifier. In addition, the 0.1-µF capacitor should be placed as close as possible to the supply
terminal. As this distance increases, the inductance in the connecting trace makes the capacitor less
effective. The designer should strive for distances of less than 0.1 inches between the device power
terminals and the ceramic capacitors.
DSockets—Sockets can be used but are not recommended. The additional lead inductance in the socket pins
will often lead to stability problems. Surface-mount packages soldered directly to the printed-circuit board
is the best implementation.
DShort trace runs/compact part placements—Optimum high performance is achieved when stray series
inductance has been minimized. To realize this, the circuit layout should be made as compact as possible,
thereby minimizing the length of all trace runs. Particular attention should be paid to the inverting input of
the amplifier. Its length should be kept as short as possible. This helps to minimize stray capacitance at the
input of the amplifier.
DSurface-mount passive components—Using surface-mount passive components is recommended for high
performance amplifier circuits for several reasons. First, because of the extremely low lead inductance of
surface-mount components, the problem with stray series inductance is greatly reduced. Second, the small
size of surface-mount components naturally leads to a more compact layout thereby minimizing both stray
inductance and capacitance. If leaded components are used, it is recommended that the lead lengths be
kept as short as possible.

APPLICATION INFORMATION
shutdown function
Three members of the TLV277x family (TLV2770/3/5) have a shutdown terminal for conserving battery life in
portable applications. When the shutdown terminal is tied low, the supply current is reduced to 0.8 µA/channel,
the amplifier is disabled, and the outputs are placed in a high impedance mode. To enable the amplifier, the
shutdown terminal can either be left floating or pulled high. When the shutdown terminal is left floating, care
needs to be taken to ensure that parasitic leakage current at the shutdown terminal does not inadvertently place
the operational amplifier into shutdown. The shutdown terminal threshold is always referenced to VDD/2.
Therefore, when operating the device with split supply voltages (e.g. ±2.5 V), the shutdown terminal needs to
be pulled to VDD− (not GND) to disable the operational amplifier.
The amplifier’s output with a shutdown pulse is shown in Figure 48 through Figure 50. The amplifier is powered
with a single 5-V supply and configured as a noninverting configuration with a gain of 5. The amplifier turnon
and turnoff times are measured from the 50% point of the shutdown pulse to the 50% point of the output
waveform. The times for the single, dual, and quad are listed in the data tables. The bump on the rising edge
of the TLV2770 output waveform is due to the start-up circuit on the bias generator. For the dual and quad
(TLV2773/5), this bump is attributed to the bias generator’s start-up circuit as well as the crosstalk between the
other channel(s), which are in shutdown.
Figure 55 and Figure 56 show the amplifier’s forward and reverse isolation in shutdown. The operational
amplifier is powered by ±1.35-V supplies and configured as a voltage follower (AV = 1). The isolation
performance is plotted across frequency for both 0.1-VPP and 2.7-VPP input signals. During normal operation,
the amplifier would not be able to handle a 2.7-VPP input signal with a supply voltage of ±1.35 V since it exceeds
the common-mode input voltage range (VICR). However, this curve illustrates that the amplifier remains in
shutdown even under a worst case scenario.
