Overview
The MAX1180 is a 3.3V, dual 10-bit, analog-to-digital converter (ADC) designed by Maxim Integrated. It features fully-differential wideband track-and-hold (T/H) inputs driving two pipelined, nine-stage ADCs. This device is optimized for low-power, high-dynamic performance applications in imaging, instrumentation, and digital communication.
