General Description
The MAX5822 is a dual, 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 115μA at V
DD
= 3.6V. A power-down mode
decreases current consumption to less than 1μA. The
MAX5822 features three software-selectable power-
down output impedances: 100k
, 1k
, and high imped-
ance. Other features include internal precision
Rail-to-Rail
output buffers and a power-on reset (POR)
circuit that powers up the DAC in the 100k
power-down
mode.
The MAX5822 features a double-buffered I
2
C-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 inter-
facing to optocoupled and transformer-isolated inter-
faces. The MAX5822 minimizes digital noise feedthrough
by disconnecting the clock (SCL) signal from the rest of
the device when an address mismatch is detected.
The MAX5822 is specified over the extended tempera-
ture range of -40°C to +85°C and is available in a minia-
ture 8-pin μMAX package. Refer to the MAX5821 data
sheet for the 10-bit version.
