Overview
The MAX1197ECM+D, produced by Analog Devices Inc./Maxim Integrated, is a 3V, dual, 8-bit analog-to-digital converter (ADC) designed for low-power, small size, and high-dynamic performance. This ADC is optimized for applications in imaging, instrumentation, and digital communications. It operates from a single 2.7V to 3.6V supply and consumes only 120mW while delivering a typical signal-to-noise and distortion (SINAD) of 48.5dB at an input frequency of 30MHz and a sampling rate of 60Msps.
