ADA4523-1BRMZ

Overview

The EVAL-ADA4523-1BRMZ is an evaluation board designed for the ADA4523-1, a high voltage, low noise, zero drift operational amplifier manufactured by Analog Devices Inc. This single-channel device operates within a supply voltage range of 4.5 V to 36 V. It features a typical gain bandwidth product of 5 MHz and a slew rate of 1.85 V/µs rising. The amplifier delivers a maximum offset voltage of ±4 µV at 5 V with a drift of 0.01 µV/°C. Input bias current is typically 300 pA, and supply current per amplifier is 4.5 mA. The board supports testing in 8-lead SOIC packages.
