Product Introduction

Overview

The LTC2281IUP, manufactured by Analog Devices Inc., is a dual 10-bit, 125Msps low power 3V analog-to-digital converter (ADC). This device is designed for digitizing high frequency, wide dynamic range signals, making it ideal for demanding imaging and communications applications. It operates on a single 3V supply, enabling low power operation, and features a separate output supply that allows the outputs to drive logic levels from 0.5V to 3.6V.
