Overview
The LTC2373CUH-16#PBF 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 low noise and high-speed applications, operating from a single 5V supply. It features an 8-channel input multiplexer with low crosstalk, supporting fully differential, pseudo-differential unipolar, and pseudo-differential bipolar analog input ranges. The LTC2373-16 achieves high accuracy with ±1LSB INL (maximum) in all input ranges, no missing codes at 16 bits, and a signal-to-noise ratio (SNR) of 96dB (fully differential) and 93.4dB (pseudo-differential).
