Overview
The MAX12558ETK+TD, produced by Analog Devices Inc./Maxim Integrated, is a highly advanced dual analog-to-digital converter (ADC) designed for high-performance applications. This component features fully differential wideband track-and-hold (T/H) inputs and is optimized for low power consumption, small size, and high dynamic performance. It is particularly suited for intermediate frequency (IF) and baseband sampling applications.
The MAX12558ETK+TD operates from a single 3.3V supply and consumes only 756mW while delivering a typical 71.7dB signal-to-noise ratio (SNR) at a 175MHz input frequency. The device includes a flexible reference structure that allows the use of an internal 2.048V bandgap reference or an externally applied reference, which can be shared between the two ADCs.
