General Description

The MAX1186 is a 3V, dual 10-bit analog-to-digital converter (ADC) featuring fully-differential wideband trackand-hold (T/H) inputs, driving two pipelined, nine-stage ADCs. The MAX1186 is optimized for low-power, high dynamic performance applications in imaging, instrumentation, and digital communication applications. This ADC operates from a single 2.7V to 3.6V supply, consuming only 105mW while delivering a typical signal-tonoise ratio (SNR) of 59.4dB at an input frequency of 20MHz and a sampling rate of 40Msps.
