MAX5864ETM+

Analog Front End (AFE) Overview

The MAX5864ETM+ is an ultra-low-power analog front end integrating dual 8-bit receive ADCs and dual 10-bit transmit DACs. It operates at a maximum clock frequency of 22Msps with a +2.7V to +3.3V analog supply and +1.8V to +3.3V digital I/O supply. In transceiver mode at 22Msps, typical power consumption is 42mW. The ADCs provide 48.5dB SINAD and 69dBc SFDR at fIN = 5.5MHz. The DACs deliver 71.7dBc SFDR and 57dB SNR at fOUT = 2.2MHz. The device features an internal 1.024V reference and is housed in a 48-pin thin QFN package.
