AD524 is a precision monolithic instrumentation amplifier designed by Analog Devices for data acquisition applications requiring high accuracy under worst-case operating conditions. It features outstanding combination of high linearity, high common mode rejection, low offset voltage drift, and low noise.
The AD524 precision instrumentation amplifier is designed for high‑accuracy data‑acquisition systems. It offers low noise (0.3 mV p‑p from 0.1 Hz to 10 Hz), low offset voltage (50 mV), and a gain‑bandwidth product of 25 MHz.
The device is available in multiple temperature‑grade packages (A, B, C, S) and in 16‑pin DIP, SOIC, and leadless chip carrier formats. Fixed gains of 1, 10, 100 and 1000 are pin‑programmable without external components, and any gain between 1 and 1000 can be set with a single external resistor.
