Overview
The MAX1186ECM+TD is a 3V, dual 10-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device features fully-differential wideband track-and-hold (T/H) inputs, driving two pipelined, nine-stage ADCs. It is optimized for low-power, high dynamic performance applications in various fields such as imaging, instrumentation, and digital communication. The MAX1186 operates from a single 2.7V to 3.6V supply, consuming only 105mW while delivering a typical signal-to-noise ratio (SNR) of 59.4dB at an input frequency of 20MHz and a sampling rate of 40Msps.
