General Description

The MAX5712 is a small footprint, low-power, 12-bit digital-to-analog converter (DAC) that operates from a single +2.7V to +5.5V supply. The MAX5712 on-chip precision output amplifier provides rail-to-rail output swing. Drawing only 85μA supply current at +3V, the MAX5712 is ideally suited for portable battery-operated equipment.
