Product Introduction

Overview

The LTC2389IUK-16#PBF is a high-performance, 16-bit successive approximation register (SAR) analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is designed for high-speed and low-noise applications, operating from a single 5V supply. It supports multiple analog input ranges, including fully differential (±4.096V), pseudo-differential unipolar (0V to 4.096V), and pseudo-differential bipolar (±2.048V), making it versatile for various signal chain formats without the need for additional level translation or signal conditioning.
