Product Introduction

Overview

The AD7381BCPZ-RL7, produced by Analog Devices Inc., is a 14-bit dual simultaneous sampling, high-speed, low-power successive approximation register (SAR) analog-to-digital converter (ADC). This device operates from a 3.0 V to 3.6 V power supply and features throughput rates up to 4 MSPS. It is part of the AD7380/AD7381 family, which is known for its pin compatibility and high-performance characteristics. The AD7381 includes an integrated on-chip oversampling block that enhances dynamic range and reduces noise at lower bandwidths, making it suitable for a variety of applications requiring precise and efficient data conversion.
