The MAX5812MEUT+T is a 12bit low power, 2wire, serial voltage output DAC in 6 pin SOT-23 package. It is a single, 12bit voltage output DAC with an I2C compatible 2-wire interface that operates at clock rates up to 400KHz. A low power, power-down mode decreases current consumption to less than 1μA. The MAX5812 features three software-selectable power-down output impedances of 100Kohm, 1Kohm 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 100Kohm power-down mode. The MAX5812 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 MAX5812 minimizes digital noise feed through by disconnecting the clock signal from the rest of the device when an address mismatch is detected.
