ADA4922-1ACPZ-R2

Overview

The ADA4922-1ACPZ-R2 is a high-voltage differential amplifier manufactured by Analog Devices Inc., designed to drive 16-bit to 18-bit analog-to-digital converters with differential input ranges up to ±20 V. It converts single-ended signals to differential outputs with a fixed gain of 2, requiring no external gain components. The device operates on supply voltages ranging from 5 V to 26 V and delivers differential output signals exceeding 40 V p-p. Key electrical specifications include a small-signal bandwidth of 38 MHz at low amplitudes, a slew rate of 730 V/µs for large steps, and a maximum differential output offset voltage of 1.1 mV. It features an integrated disable function and operates within an extended industrial temperature range of -40°C to +85°C.
