Overview
The MAX12559ETK+ is a high-performance, dual, 14-bit analog-to-digital converter (ADC) designed by Analog Devices Inc./Maxim Integrated. This component is optimized for low power consumption, small size, and high dynamic performance, making it ideal for intermediate frequency (IF) and baseband sampling applications. It operates from a single 3.3V supply, consuming only 980mW while delivering a typical 72.2dB signal-to-noise ratio (SNR) at a 175MHz input frequency. The ADC features fully differential wideband track-and-hold (T/H) inputs and supports both single-ended and differential inputs up to 350MHz.
