19-2270; Rev 1; 11/04
10-Bit, Low-Power, 2-Wire Interface, Serial,
Voltage-Output DAC
General Description
The MAX5811 is a single, 10-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 MAX5811 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 (POR)
circuit that powers up the DAC in the 100kpower-down
mode.
The MAX5811 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
MAX5811 minimizes digital noise feedthrough by discon-
necting the clock (SCL) signal from the rest of the device
when an address mismatch is detected.
The MAX5811 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 MAX5812 data
sheet for the 12-bit version.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
