9.1 Application Information

The PGA855 is a monolithic, high-voltage, high bandwidth, precision programmable gain instrumentation amplifier with fully differential outputs. The PGA855 combines a high-speed current-feedback input stage with an internally matched gain resistor network, followed by a four-resistor, fully differential amplifier output stage. The PGA855 is equipped with 8 binary-gain settings, from 0.125 V/V to 16 V/V, using three digital gain-selection pins: A0, A1, and A2.

The PGA855 is designed to work with applications such as factory automation and control, analog input modules, data acquisition, test and measurement, and semiconductor test.
