Overview
The LTC2311-16, produced by Analog Devices Inc., is a high-performance, 16-bit successive approximation register (SAR) analog-to-digital converter (ADC). This component is designed for applications requiring high speed, low noise, and a wide dynamic range. It operates from a single 3.3V or 5V supply and features differential inputs with an 8V peak-to-peak differential input range, making it ideal for high common mode rejection and wide input common mode range applications.
