AD8390ACPZ-R2

Instrumentation, Op Amps, Buffer Amps Overview

The AD8390ACPZ-R2 is a low power, high output current differential amplifier manufactured by Analog Devices Inc. It operates on single or dual supplies ranging from 10 V to 24 V. The device provides a 400 mA peak output drive current and a 44.2 V p-p differential output voltage. It features a 300 V/µs slew rate and a 60 MHz small signal bandwidth. Quiescent current ranges from 0.57 mA to 11.0 mA depending on the PWDN mode and IADJ configuration. Harmonic distortion is specified at -82 dBc for the second harmonic and -91 dBc for the third harmonic at 1 MHz.
