Overview
The LTC2373IUH-16 is a high-performance, low noise, and high-speed analog-to-digital converter (ADC) produced by Analog Devices Inc. This 16-bit successive approximation register (SAR) ADC operates from a single 5V supply and features an 8-channel input multiplexer. It supports fully differential, pseudo-differential unipolar, and pseudo-differential bipolar analog input ranges, making it highly versatile for various applications. The LTC2373IUH-16 is known for its excellent signal-to-noise ratio (SNR) of up to 96dB in fully differential mode and 93.4dB in pseudo-differential mode, along with no missing codes at 16 bits and a maximum integral nonlinearity (INL) of ±1LSB.
