Overview
The MAX1195ECM, produced by Analog Devices Inc./Maxim Integrated, is a 3V, dual, 8-bit analog-to-digital converter (ADC) designed for low-power, high-dynamic performance, and small size. This ADC is optimized for applications in imaging, instrumentation, and digital communications. It operates from a single 2.7V to 3.6V supply and features fully differential wideband track-and-hold (T/H) inputs driving two ADCs.
