The ADA4622-1/ADA4622-2/ADA4622-4 include many improvements that make them desirable as upgrades without compromising the flexibility and ease of use that makes the AD820/AD822/AD824 useful for a wide variety of applications. The input voltage range includes the negative supply and the output swings rail-to-rail. Input EMI filters increase the signal robustness in the face of closely located switching noise sources. The speed, in terms of bandwidth and slew rate, increases along with a strong output drive to improve settling time performance and enables the devices to drive the inputs of modern singleended, successive approximation register (SAR) analog-todigital converters (ADCs). Rev. E Voltage noise is reduced; although the supply current remains the same as the AD820/AD822/AD824, broadband noise is reduced by 25%, and 1/f is reduced by half. DC precision in the ADA4622-1/ADA4622-2/ADA4622-4 improved from the AD820/AD822/AD824 with half the offset and a maximum thermal drift specification added to the ADA4622-1/ADA4622-2/ ADA4622-4. The common-mode rejection ratio (CMRR) is improved from the AD820/AD822/AD824 to make the ADA4622-1/ADA4622-2/ADA4622-4 more suitable when used in noninverting gain and difference amplifier configurations. The ADA4622-1/ADA4622-2/ADA4622-4 are specified for operation over the extended industrial temperature range of -40C to +125C, and operate from 5 V to 30 V, with specifications at +5 V, 5 V, and 15 V. The ADA4622-1 is available in a 5-lead SOT-23 package and an 8-lead LFCSP package. The ADA4622-2 is available in an 8-lead SOIC_N package, an 8-lead MSOP package, and an 8-lead LFCSP package. The ADA4622-4 is available in a 14-lead SOIC_N and a 16-lead, 4 x 4 mm LFCSP. Document Feedback Information furnished by Analog Devices is believed to be accurate and reliable.

Simplified Circuit Diagram INPUT CHARACTERISTICS The ADA4622-1/ADA4622-2/ADA4622-4 input stage consists of N-channel JFETs that provide low offset, low noise, and high impedance. The minimum input common-mode voltage extends from -0.2 mV below V- to 1 V less than V+. Driving the input closer to the positive rail causes loss of amplifier bandwidth and increased common-mode voltage error. Figure 81 shows the rounding of the output due to the loss of bandwidth.

No Phase Reversal Because the input stage uses N-channel JFETs, the input current during normal operation is negative. However, the input bias current changes direction as the input voltage approaches V+ due to internal junctions becoming forward-biased (see Figure 83). 1 13502-076 4 A CH1 3.00V Figure 81.

This noise performance, along with the low input current as well as low current noise, means that the ADA4622-1/ADA4622-2/ ADA4622-4 contribute negligible noise for applications with a source resistance greater than 10 k and at signal bandwidths greater than 1 kHz. 100 COMPETITOR 1 COMPETITOR 2 ADA4622-1/ADA4622-2/ADA4622-4 EMIRR (dB) 80 60 40 100k 13502-080 20 0 10M 100M 1G FREQUENCY (Hz) Figure 85.

Total Noise vs. Source Resistance and Frequency Input Overvoltage Protection The ADA4622-1/ADA4622-2/ADA4622-4 have internal protective circuitry that allows voltages as high as 0.3 V beyond the supplies applied at the input of either terminal without causing damage. Use a current-limiting resistor in series with the input of the ADA4622-1/ADA4622-2/ADA4622-4 if the input voltage exceeds 0.3 V beyond the supply rails of the amplifiers. If the overvoltage condition persists for more than a few seconds, damage to the amplifiers can result. For higher input voltages, determine the resistor value by VIN - VSY 10 mA RS where: VIN is the input voltage. VSY is the voltage of either the V+ pin or the V- pin. RS is the series resistor. The ADA4622-1/ADA4622-2/ADA4622-4 unique bipolar railto-rail output stage swings within 10 mV of the supplies with no external resistive load. The approximate output saturation resistance of the ADA4622-1/ ADA4622-2/ADA4622-4 is 24 , sourcing or sinking. Use the output impedance to estimate the output saturation voltage when driving heavier loads. As an example, when driving 5 mA, the saturation voltage from either rail is approximately 120 mV. If the ADA4622-1/ADA4622-2/ADA4622-4 output drives hard against the output saturation voltage, it recovers within 1.2 s of the input, returning to the linear operating region of the amplifier (see Figure 56 and Figure 59). Capacitive Load Drive Capability Direct capacitive loads interact with the effective output impedance of the ADA4622-1/ADA4622-2/ADA4622-4 to form an additional pole in the feedback loop of the amplifiers, which causes excessive peaking on the pulse response or loss of stability. The worst case condition is when the devices use a single 5 V supply in a unity-gain configuration. Figure 86 shows the pulse response of the ADA4622-1/ADA4622-2/ADA4622-4 when driving 500 pF directly. 1 13502-081 With a very low input bias current of 1.5 nA maximum up to 125C, higher resistor values can be used in series with the inputs without introducing large offset errors. A 1 k series resistor allows the ADA4622-1/ADA4622-2/ADA4622-4 to withstand 10 V of continuous overvoltage and increases the noise by a negligible amount. A 5 k resistor protects the inputs from voltages as high as 25 V beyond the supplies and adds less than 10 V to the offset voltage of the amplifiers.

When the voltage on the DISABLE input is less than 1.4 V above the negative supply voltage (V-), the ADA4622-1 shuts down and consumes only 50 A to 60 A (typical). When the voltage on the DISABLE input is more than 1.4 V above the negative supply voltage (V-), or if the DISABLE input is left floating, the ADA4622-1 powers up. For best performance, it is recommended that the input voltage level on the DISABLE input be V- or that the input be left floating. The ADA4622-1 is still a drop-in replacement for devices with standard single channel op amp pinouts because the ADA4622-1 enables when the DISABLE input is left floating.

Both low dropout (LDO) regulators are available in fixed output voltage or adjustable output voltage versions. To generate the input voltages for the LDOs, the ADP5070 dc-to-dc switching regulator is recommended.

Data Sheet ADA4622-1/ADA4622-2/ADA4622-4 The following basic transfer function describes the transimpedance gain of the photodiode preamplifier: OPEN-LOOP GAIN I PHOTO x RF 1 + sC F RF where: IPHOTO is the output current of the photodiode. The parallel combination of RF and CF sets the signal bandwidth (see the I to V gain trace in Figure 96). s refers to the s-plane. Note that RF must be set so the maximum attainable output voltage corresponds to the maximum diode output current, IPHOTO, which allows use of the full output swing. The attainable signal bandwidth with this photodiode preamplifier is a function of RF, the gain bandwidth product (fGBP) of the amplifier, and the total capacitance at the amplifier summing junction, including CS and the amplifier input capacitance, CD and CM. RF and the total capacitance produce a pole with loop frequency (fP). fX I TO V GAIN fZ G = 1 + CS/CF G = RFCS(s) G=1 f fp fGBP 90 45 f 0 1 2R F C S With the additional pole from the amplifier open-loop response, the two-pole system results in peaking and instability due to an insufficient phase margin (see Figure 95). fN -45 -90 13502-087 fP = |A (s)| VOUT = OPEN-LOOP GAIN -135 Figure 96. Gain and Phase Plot of the Transimpedance Amplifier Design with Compensation |A| (dB) Adding CF creates a zero in the loop transmission that compensates for the effect of the input pole, which stabilizes the photodiode preamplifier design because of the increased phase margin. Adding CF also sets the signal bandwidth (see Figure 96). The signal bandwidth and the zero frequency are determined by fX G = R2C1s G=1 fZ = log f fP fGBP 1 2 RF C F where fZ is the zero frequency. Setting the zero at the fX frequency maximizes the signal bandwidth with a 45 phase margin.

E | Page 31 of 38 ADA4622-1/ADA4622-2/ADA4622-4 Data Sheet The dominant sources of output noise in the wideband photodiode preamp design are the input voltage noise of the amplifier, VNOISE, and the resistor noise due to RF.

By taking advantage of the dc precision and super low input bias current of the JFET input amplifiers, such as the ADA4622-1/ADA4622-2/ADA4622-4, a highly accurate peak detector can be built, as shown in Figure 99. By using the ADA4622-1 DISABLE input, it is possible to multiplex two inputs to a single output by using the circuit shown in Figure 100. If the gain configuration or filter configuration of the two amplifiers is different, and a common single input to both amplifiers is used, this configuration can control selectable gain or selectable frequency response at the output. + 2 8 ADA4622-1/ ADA4622-2/ ADA4622-4 U1 V- 5 1 4 - VIN V+ C4 50pF D3 1N4148 D4 1N4148 6 C3 1F R7 10k D2 1N448 8 ADA4622-1/ ADA4622-2/ ADA4622-4 U2 +PEAK V+ 3 7 + 4 2 7 ADA4622-1 6 U1 8 4 - V V- R6 1k V- VOUT DISABLE V Figure 99.

Multiplexed Input Circuit Figure 101 shows the output response when multiplexing two input signals. The input to the first amplifier is a 4 V p-p, 200 kHz sine wave; the input to the second amplifier is an 8 V p-p, 100 kHz sine wave. The ADA4622-1/ADA4622-2/ADA4622-4, shown in Figure 99, are a perfect fit for building a peak detector because U1 requires dc precision and high output current during fast peaks, and U2 requires low input bias current (IB) to minimize capacitance discharge between peaks. A low leakage and low dielectric absorption capacitor, such as polystyrene or polypropylene, is required for C3. Reversing the diode directions causes the circuit to detect negative peaks. OUTPUT VOLTAGE Feedback from the output of the U2 (positive peak) through R6 limits the output voltage of U1. After detecting the peak, the output of U1 swings low but is clamped by D2. D3 reverses bias and the common node of D3, D4, and R7 is held to a voltage equal to positive peak by R7. The voltage across D4 is 0 V; therefore, the leakage is small. The bias current of U2 is also small. With almost no leakage, C3 has a long hold time. 13502-298 To detect a positive peak, U1 drives C3 through D3 and drives D4 until C3 is charged to a voltage equal to the input peak value.

The circuit is composed of a voltage follower (U1) and a second stage amplifier (U2) that combine the output of the first stage amplifier and the inverted version of the input signal. U1 follows the input during the positive half cycle and clamps the negative going input signal to ground, producing a half wave signal at VHW. The following equation defines the circuit transfer function: During the input positive half cycle, U1 follows the input so that VHW = VIN; therefore, VFW = VIN. During the negative half cycle, U1 clamps the signal to ground so that VHW = 0 V; therefore, VFW = -(R3/R2) x VIN = -VIN because R3/R2 = 1. Figure 103 shows the input and outputs waveforms from the circuit. The input is a 2 V p-p, 1 kHz sine wave while the circuit is running on a 5 V single supply.
