Working Principle of INA132UA

The INA132UA uses the classic three-op-amp topology to implement an instrumentation amplifier circuit. Two of the amplifiers are used to form a differential amplifier, while the third amplifier is used as an output buffer. The differential amplifier amplifies the difference between the two input signals, and the output buffer buffers and amplifies the differential signal. The gain of the amplifier is determined by the ratio of the resistors connected to the non-inverting and inverting input terminals.

The INA132UA also has several features that improve its performance. For example, the device has an internal frequency compensation circuit, which reduces the effects of frequency-dependent gain errors. It also has a selectable reference voltage, which allows the user to adjust the output offset voltage. Finally, the device also has an open-loop gain correction network, which reduces gain errors caused by mismatches between transistors in the amplifier circuit.
