Product Introduction

Overview

The AD8138ARMZ from Analog Devices Inc. is a high-performance, low-distortion differential amplifier designed for differential signal processing. It can be used as a single-ended-to-differential amplifier or as a differential-to-differential amplifier. Manufactured on the proprietary ADI XFCB bipolar process, the AD8138 simplifies differential signal amplification and driving, making it as easy to use as an op amp. It features a unique internal feedback circuit that provides balanced output gain and phase matching, suppressing even order harmonics and minimizing gain errors associated with external gain setting resistors.
