General Description
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 100A at VDD = 3.6V. A low-power power-
down mode decreases current consumption to less than
1A. 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 I2C-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.
