7.1.2 Transfer Function

Most applications use the INA117 as a simple unity-gain difference amplifier. The transfer function is:

V0 = V3 – V2

V3 and V2 are the voltages at pins 3 and 2.

Some applications, however, apply voltages to the reference terminals (pins 1 and 5). A more complete transfer function is:

V0 = V3 – V2 + 19 × V5 – 18 × V1

V5 and V1 are the voltages at pins 5 and 1.
