Overview
The LTC2389-16, produced by Analog Devices Inc., is a high-performance, low-noise, 16-bit successive approximation register (SAR) analog-to-digital converter (ADC). This device operates from a single 5V supply and is designed to support a variety of high-speed applications. It features pin-configurable analog input ranges, including fully differential (±4.096V), pseudo-differential unipolar (0V to 4.096V), and pseudo-differential bipolar (±2.048V), allowing for flexible integration into different signal chain formats without the need for additional level translation or signal conditioning.
