DESCRIPTION

The DG406 is a 16-channel single-ended analog multiplexer

designed to connect one of sixteen inputs to a common

output as determined by a 4-bit binary address. The DG407

selects one of eight differential inputs to a common

differential output. Break-before-make switching action

protects against momentary shorting of inputs.

An on channel conducts current equally well in both

directions. In the off state each channel blocks voltages up

to the power supply rails. An enable (EN) function allows the

user to reset the multiplexer/demultiplexer to all switches off

for stacking several devices. All control inputs, address (Ax)

and enable (EN) are TTL compatible over the full specified

operating temperature range.

Applications for the DG406/407 include high speed data

acquisition, audio signal switching and routing, ATE

systems, and avionics. High performance and low power

dissipation make them ideal for battery operated and remote

instrumentation applications. For additional application

information order Faxback document numbers 70601 and

70604.

Designed in the 44 V silicon-gate CMOS process, the

absolute maximum voltage rating is extended to 44 volts,

allowing operation with ± 20 V supplies. Additionally single

(12 V) supply operation is allowed. An epitaxial layer

prevents latchup.

For applications information please request FaxBack

documents 70601 and 70604.

a. Refer to PROCESS OPTION FLOWCHART.

b. Room = 25 °C, Full = as determined by the operating temperature suffix.

c. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.

d. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.

e. Guaranteed by design, not subject to production test.

f. VIN = input voltage to perform proper function.

g. ΔrDS(on) = rDS(on) MAX - rDS(on) MIN.

h. Worst case isolation occurs on Channel 4 due to proximity to the drain pin.

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 in the operational sections of the specifications is not implied. Exposure to absolute maximum

rating conditions for extended periods may affect device reliability.

DG406/407

APPLICATIONS HINTS

Sampling speed is limited by two consecutive events: the

transition time of the multiplexer, and the settling time of the

sampled signal at the output.

tTRANS is given on the data sheet. Settling time at the load

depends on several parameters: rDS(on) of the multiplexer,

source impedance, multiplexer and load capacitances,

charge injection of the multiplexer and accuracy desired.

The settling time for the multiplexer alone can be derived

from the model shown in Figure 5. Assuming a low

impedance signal source like that presented by an op amp or

a buffer amplifier, the settling time of the RC network for a

given accuracy is equal to nτ:

The maximum sampling frequency of the multiplexer is:

(1)

where N = number of channels to scan

tSETTLING = nτ = n x rDS(on) x CD(on)

For the DG406 then, at room temp and for 12-bit accuracy,

using the maximum limits:

(2)

fs = 694 kHz (3)

From the sampling theorem, to properly recover the original

signal, the sampling frequency should be more than twice

the maximum component frequency of the original signal.

This assumes perfect bandlimiting. In a real application

sampling at three to four times the filter cutoff frequency is a

good practice.

Therefore from equation 2 above:

(4)

From this we can see that the DG406 can be used to sample

16 different signals whose maximum component frequency

can be as high as 173 kHz. If for example, two channels are

used to double sample the same incoming signal then its

cutoff frequency can be doubled.

DG406/407

APPLICATIONS HINTS

The block diagram shown in Figure 6 illustrates a typical data

acquisition front end suitable for low-level analog signals.

Differential multiplexing of small signals is preferred since

this method helps to reject any common mode noise. This is

especially important when the sensors are located at a

distance and it may eliminate the need for individual

amplifiers. A low rDS(on), low leakage multiplexer like the

DG407 helps to reduce measurement errors. The low power

dissipation of the DG407 minimizes on-chip thermal

gradients which can cause errors due to temperature

mismatch along the parasitic thermocouple paths. Please

refer to Application Note AN203 for additional information.
