Product Introduction

Overview

The LTC2372IUH-16 is a high-performance, low noise, and high-speed 8-channel 16-bit successive approximation register (SAR) analog-to-digital converter (ADC) produced by Analog Devices, Inc. This ADC operates from a single 5V supply and features a highly configurable, low crosstalk 8-channel input multiplexer. It supports fully differential, pseudo-differential unipolar, and pseudo-differential bipolar analog input ranges. The LTC2372IUH-16 achieves ±1LSB INL (maximum) in all input ranges, with no missing codes at 16 bits and a signal-to-noise ratio (SNR) of 96dB (fully differential) and 93.5dB (pseudo-differential).
