    General Description
    The MAX5812 is a single, 12-bit voltage-output, digital-to-
    analog converter (DAC) with an I
    2
    C-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 V
    DD
    = 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: 100k
    , 1k
    , 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 100k
    power-down mode.
    The MAX5812 features a double-buffered I
    2
    C-compatible
    serial interface that allows multiple devices to share a sin-
    gle 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 discon-
    necting 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-sav-
    ing 6-pin SOT23 package. Refer to the MAX5811 for the
    10-bit version.
