General Description

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