Overview
The MAX12527ETK+D, produced by Analog Devices Inc./Maxim Integrated, is a dual 3.3V, 12-bit analog-to-digital converter (ADC) designed for high-performance applications. This ADC features fully differential wideband track-and-hold (T/H) inputs and is optimized for low power consumption, small size, and high dynamic performance in intermediate frequency (IF) and baseband sampling applications. It operates from a single 3.3V supply, consuming only 620mW while delivering a typical 69.8dB signal-to-noise ratio (SNR) at a 175MHz input frequency.
