General Description

The MAX5812 is a single, 12-bit voltage-output, digital-to-analog converter (DAC) with an I2C?-compatible 2-wire interface that operates at clock rates up to 400kHz. The device operates from a single 2.7V to 5.5V supply and draws only 100μA at VDD = 3.6V. A low-power power-down mode decreases current consumption to less than 1μA. The MAX5812 features three software-selectable power-down output impedances: 100k?, 1k?, and high impedance. Other features include an internal precision Rail-to-Rail? output buffer and a power-on reset circuit that powers up the DAC in the 100k? power-down mode.
