Overview
The MAX1444EHJ+ is a 10-bit, 3V analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device features a pipelined 10-stage ADC architecture with a fully differential wideband track-and-hold (T/H) input and digital error correction. It is optimized for low-power, high dynamic performance applications, particularly in imaging and digital communications. The MAX1444 operates from a single 2.7V to 3.6V supply, consuming only 57mW while delivering a 59.5dB signal-to-noise ratio (SNR) at a 20MHz input frequency.
