THREE OP AMP
INSTRUMENTATION AMPLIFIER
A classic, three op amp instrumentation amplifier is
illustrated in Figure 4-12. The two input op amps
provide differential signal gain and a common mode
gain of +1. The output op amp is a difference amplifier,
which converts its input signal from differential to a sin-
gle ended output; it rejects common mode signals at its
input. The gain of this circuit is simply adjusted with one
resistor (RG). The reference voltage (VREF) is typically
referenced to mid-supply (VDD/2) in single-supply
applications.

PRECISION GAIN WITH GOOD
LOAD ISOLATION
provide a high gain to the input signal (VIN). The
MCP606’s low offset voltage makes this an accurate
circuit.
The MCP601 is configured as a unity-gain buffer. It
isolates the MCP606’s output from the load, increasing
the high-gain stage’s precision. Since the MCP601 has
a higher output current, with the two amplifiers being
housed in separate packages, there is minimal change
in the MCP606’s offset voltage due to loading effect.
