The MAX5812 is a single, 12-bit voltage-output, digital-to-analog converter (DAC) 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 100µA at VDD = 3.6V. A low-power power-down 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-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 feedthrough by disconnecting the clock (SCL) signal from the rest of the device when an address mismatch is detected. The MAX5812 is specified over the extended temperature range of -40°C to +85°C and is available in a space-saving 6-pin SOT23 package. Refer to the MAX5811 for the 10-bit version.
