Overview
The MAX12554ETL+T, produced by Analog Devices Inc./Maxim Integrated, is a 3.3V, 14-bit, 80Msps analog-to-digital converter (ADC) designed for high dynamic performance, low power consumption, and compact size. This ADC features a fully differential wideband track-and-hold (T/H) input amplifier and a low-noise internal quantizer. It is optimized for intermediate frequency (IF) sampling applications and maintains excellent dynamic performance from baseband to input frequencies of 175MHz and beyond.
