Two op amp instrumentation amplifier circuit
CIRCUIT060025
Overview
This design amplifiers the difference between Vi1 and Vi2 and outputs a single ended signal while rejecting the common–mode voltage. Linear operation of an instrumentation amplifier depends upon the linear operation of its primary building block: op amps. An op amp operates linearly when the input and output signals are within the device’s input common–mode and output–swing ranges, respectively. The supply voltages used to power the op amps define these ranges.
