Overview
The MAX12553ETL+T is a 14-bit, 65Msps analog-to-digital converter (ADC) designed by Analog Devices Inc./Maxim Integrated. This device is optimized for low power consumption, small size, and high dynamic performance, making it ideal for various high-speed data acquisition applications. The MAX12553 operates from a single 3.15V to 3.60V supply and features a fully differential wideband track-and-hold (T/H) input amplifier, driving a low-noise internal quantizer. It supports both single-ended and differential analog input signals and is particularly suited for intermediate-frequency (IF) sampling applications.
