MAX5812
Description
The MAX5812 is a single, 12-bit voltage-output, digital-toanalog converter (DAC) with an I2C™-patible 2-wire interface that operates at clock rates up to 400k Hz. The device operates from a single 2.7V to 5.5V supply and draws only 100µA at VDD = 3.6V. A low-power powerdown mode decreases current consumption to less than 1µA. The MAX5812 features three software-selectable power-down output impedances: 100kΩ, 1kΩ, 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 100kΩ power-down mode. The MAX5812 features a double-buffered I2C-patible serial interface that allows multiple devices to share a single bus. All logic inputs are CMOS-logic patible and buffered with Schmitt triggers, allowing direct interfacing to optocoupled and transformer-isolated interfaces. The MAX5812 minimizes digital noise feedthrough by disconnecting the clock (SCL) signal from the rest of the device when...
