AD582KD

Instrumentation, Op Amps, Buffer Amps Overview

The AD582KD is a low-cost integrated circuit sample and hold amplifier manufactured by Analog Devices Inc. It consists of a high-performance operational amplifier, a low leakage analog switch, and a JFET integrating amplifier fabricated on a single monolithic chip. An external holding capacitor completes the function. The device operates within a supply voltage range of 18 V to 44 V. Key electrical parameters include a slew rate of 3V/µs, a -3dB bandwidth of 1.5 MHz, an input bias current of 1.5 µA, and an input offset voltage of 2 mV. It draws 3mA of supply current and provides 25 mA of output current per channel.
