Overview
The LTC2311HMSE-16#WTRPBF is a high-performance, 16-bit successive approximation register (SAR) analog-to-digital converter (ADC) produced by Analog Devices Inc. This component is designed for high-speed applications, offering a sampling rate of up to 5 million samples per second (Msps). It features differential inputs and a wide input common mode range, making it ideal for applications requiring high dynamic range and common mode rejection.
The LTC2311HMSE-16#WTRPBF operates from a single 3.3V or 5V supply and includes an onboard low-drift (20ppm/°C max) 2.048V or 4.096V temperature-compensated reference. It also supports an external 1.25V buffered reference input. The device is available in a 16-lead MSOP package and is suitable for a variety of high-speed applications due to its fast throughput and low power consumption.
