Product Introduction

Overview

The AD8015AR, produced by Analog Devices Inc., is a wideband, single-supply transimpedance amplifier designed for use in fiber optic receiver circuits. It offers a complete, single-chip solution for converting photodiode current into a differential voltage output. With a bandwidth of 240 MHz, the AD8015AR supports data rates up to 155 Mbps and beyond, making it suitable for applications in SONET/SDH, FDDI, and Fibre Channel systems. The amplifier is known for its low cost, low noise, and wide dynamic range, making it an attractive alternative to GaAs-based transimpedance amplifiers.
