Overview
The LTC2372-16, produced by Analog Devices Inc., is a high-performance, low-noise, 16-bit successive approximation register (SAR) analog-to-digital converter (ADC). This component operates from a single 5V supply and features an 8-channel input multiplexer with highly configurable and low crosstalk capabilities. It supports fully differential, pseudo-differential unipolar, and pseudo-differential bipolar analog input ranges. The LTC2372-16 is known for its high speed and precision, achieving ±1LSB INL (maximum) in all input ranges and no missing codes at 16 bits. It also boasts a high signal-to-noise ratio (SNR) of 96dB (fully differential) and 93.5dB (pseudo-differential).
