Product Introduction

Overview

The LTC2389-16#PBF, produced by Analog Devices Inc., is a high-performance 16-bit successive approximation register (SAR) analog-to-digital converter (ADC). This device is designed for low noise and high-speed 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.
