Figure 31. Temperature Measurement with Two Remote Sensors
Programmable-Gain Instrumentation
Amplifier
Two op amps and two SPDT switches are configured
as a programmable-gain instrumentation amplifier in
Figure 32. It includes a differential input and a single-
ended output. SPDT1 and SPDT2 are configured as
single-pole, double-throw switches. The gain is set by
the following equations:
for switch position 1, and
for switch position 2.
