Overview
The MAX1182ECM+TD, produced by Analog Devices Inc./Maxim Integrated, is a 3V, dual 10-bit analog-to-digital converter (ADC) designed for low-power, high-dynamic performance applications. This ADC features fully-differential wideband track-and-hold (T/H) inputs driving two pipelined, 9-stage ADCs. It operates from a single 2.7V to 3.6V supply, consuming only 195mW while delivering a typical signal-to-noise ratio (SNR) of 59dB at an input frequency of 20MHz and a sampling rate of 65Msps. The device is optimized for applications in imaging, instrumentation, and digital communication.
