MAX5822LEUA+

The MAX5822LEUA+ is a dual, 12bit, low power, 2-wire, serial voltage output DAC in 8 pin µMAX package. This DAC with an I2C-compatible, 2-wire interface operates at clock rates up to 400KHz. A power-down mode decreases current consumption to less than 1μA. The MAX5822 features three software-selectable power-down output impedances of 100Kohm, 1Kohm 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 100Kohm power-down mode. It 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 MAX5822 minimizes digital noise feed through by disconnecting the clock (SCL) signal from the rest of the device when an address mismatch is detected.
