AD830AR

Overview

The AD830AR is a wideband, high-speed video differencing amplifier manufactured by Analog Devices Inc. It is designed for accurate amplification of fully differential signals while rejecting common-mode noise at high frequencies. The device features an 85 MHz unity gain bandwidth and a 360 V/μs slew rate, ensuring fast dynamic performance with a 35 ns settling time to 0.1%. It offers a wide common-mode voltage range from +12.8 V to −12 V and provides a high output drive capability of ±50 mA minimum. Key electrical specifications include a maximum input offset voltage of 3 mV, a 90 dB common-mode rejection ratio (CMRR), and low distortion characteristics. The component operates on supplies ranging from 8 V to 33 V and is housed in an SOIC-8 package.
