Overview
The LTC2385IUH-18#TRPBF is a high-performance, 18-bit successive approximation register (SAR) analog-to-digital converter (ADC) produced by Analog Devices Inc. This component is designed to offer low noise, high speed, and excellent linearity, making it ideal for a wide range of applications including high-speed imaging, instrumentation, and communications.
The ADC features a serial LVDS digital interface, which supports one-lane and two-lane output modes, allowing for optimized data rate configuration based on the application. Its no-latency operation and very low distortion at high input frequencies make it particularly suitable for high-speed control loop and communication applications.
