Product Introduction

Overview

The AD7264BSTZ-RL7, produced by Analog Devices Inc., is a high-performance, dual-channel, 14-bit successive approximation analog-to-digital converter (ADC). This device operates from a single 5 V power supply and is designed for high-speed, low-power applications. It features throughput rates of up to 1 MSPS per ADC, making it suitable for simultaneous sampling and conversion of two channels. The AD7264 is available in a 48-lead LQFP package and is RoHS compliant.
