Overview
The LTC2311HMSE-12#WTRPBF is a high-performance, 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) produced by Analog Devices Inc. This component is designed for applications requiring high speed, low noise, and wide input common mode range. It operates from a single 3.3V or 5V supply and features differential inputs, making it ideal for systems that demand high common mode rejection and a wide dynamic range.
