8.1 Application Information

The PGA854 is a monolithic, high-voltage, high-bandwidth, precision programmable gain instrumentation amplifier with fully differential outputs. The PGA854 combines a high-speed current-feedback input stage with an internally matched gain resistor network, followed by a four-resistor, differential amplifier output stage. The PGA854 is equipped with eight decade-gain settings, from 0.5V/V to 100V/V, using three digital gain-selection pins: A0, A1, and A2.

The PGA854 is designed for applications such as factory automation and control, analog input modules, data acquisition, test and measurement, and semiconductor test.
