Overview
The LTC2325-16, produced by Analog Devices Inc., is a high-performance, quad 16-bit successive approximation register (SAR) analog-to-digital converter (ADC). This component is designed for applications requiring simultaneous sampling of multiple channels with high speed and low noise. It operates from a single 3.3V or 5V supply and features differential inputs with a wide input common mode range, making it ideal for applications that demand a wide dynamic range and high common mode rejection.
