Overview
The LTC2368-16, produced by Analog Devices Inc., is a high-performance, low noise, and low power 16-bit successive approximation register (SAR) analog-to-digital converter (ADC). This component operates from a 2.5V supply and features a pseudo-differential unipolar input range with a reference voltage (VREF) that can range from 2.5V to 5.1V. It is designed for high-speed applications, offering a sampling rate of 1Msps and a signal-to-noise ratio (SNR) of 94.7dB. The LTC2368-16 is also notable for its low power consumption, consuming only 13.5mW, and its automatic power-down feature between conversions, which reduces power dissipation.
