The MAX5841 is a quad, 10-bit voltage output, digitalto-analog converter (DAC) with an I2CTM-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 230A at VDD = 3.6V. A powerdown mode decreases current consumption to less than 1A. The MAX5841 features three software-selectable power-down output impedances: 100k, 1k, and high impedance. Other features include internal precision Rail-to-Rail output buffers and a power-on reset (POR) circuit that powers up the DAC in the 100k power-down mode.
