MAX5820 Overview
The MAX5820 is a dual, 8-bit voltage-output, digital-toanalog converter (DAC) with an I 2 C -patible, 2-wire interface that operates at clock rates up to 400kHz. The device operates from a single 2.7V to 5.5V supply (115µA at VDD = 3.6V). A power-down mode decreases current consumption to less than 1µA.
