Overview
The LTC2372-16#PBF, produced by Analog Devices Inc., is a high-performance, 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 low crosstalk, supporting fully differential, pseudo-differential unipolar, and pseudo-differential bipolar analog input ranges. It is known for its low noise and high speed, achieving a signal-to-noise ratio (SNR) of 96dB in fully differential mode and 93.5dB in pseudo-differential mode. The ADC also includes an onboard low drift temperature-compensated reference and a high-speed SPI-compatible serial interface, making it versatile for various applications.
