MAX5841MEUB+T

MAX5841MEUB+T is a quad, 10bit voltage output, digital to-analogue converter 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 230µA at VDD = 3.6V. A power down mode decreases current consumption to less than 1µA. The MAX5841 features three software-selectable power-down output impedances: 100kΩ, 1kΩ, and high impedance. Other features include internal precision Rail-to-Rail® output buffers and a POR circuit that powers up the DAC in the 100kΩ power-down mode. The MAX5841 features a double-buffered I2C-compatible serial interface that allows multiple devices to share a single bus. All logic inputs are CMOS-logic compatible and buffered with Schmitt triggers, allowing direct interfacing to optocoupled and transformer-isolated interfaces. The MAX5841 minimizes digital noise feedthrough by disconnecting the clock signal from the rest of the device when an address mismatch is detected.
