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
Vishay Siliconix maintains worldwide manufacturing capability. Products may be manufactured at one of several qualified locations. Reliability data for Silicon Tech-
nology and Package Reliability represent a composite of all qualified locations. For related documents such as package/tape drawings, part marking, and reliability

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
