Overview
The MAX1195ECM+D, produced by Analog Devices Inc./Maxim Integrated, is a 3V, dual, 8-bit analog-to-digital converter (ADC) designed for low-power, small size, and high-dynamic performance. This ADC is optimized for applications in imaging, instrumentation, and digital communications. It operates from a single 2.7V to 3.6V supply, consuming only 87mW while delivering a typical signal-to-noise and distortion (SINAD) of 48.5dB at an input frequency of 20MHz and a sampling rate of 40Msps. The device features fully differential wideband track-and-hold (T/H) inputs and can also be operated with single-ended inputs.
