Product Introduction

Overview

The AD538ADZ is a monolithic real-time analog computational unit (ACU) produced by Analog Devices Inc. This device is designed to perform precision analog multiplication, division, and exponentiation. It features low input and output offset voltages and excellent linearity, enabling accurate computation over a wide input dynamic range. The AD538ADZ is particularly notable for its high accuracy, achieved through laser wafer trimming, which reduces errors to as low as 0.25% of reading. The device operates with a bandwidth of 400 kHz, enhancing real-time analog signal processing capabilities.
