Overview
The MAX1181ECM+D, 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 device features fully-differential wideband track-and-hold (T/H) inputs driving two pipelined, nine-stage ADCs. It operates from a single 2.7V to 3.6V supply, consuming only 246mW, and delivers a typical signal-to-noise ratio (SNR) of 59dB at an input frequency of 20MHz and a sampling rate of 80Msps. The MAX1181 is optimized for applications in imaging, instrumentation, and digital communication.
