The MAX5811 is a single, 10-bit voltage-output digital-to-

analog converter (DAC) with an I

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

down mode decreases current consumption to less than

1µA. The MAX5811 features three software-selectable

power-down output impedances: 100kΩ, 1kΩ, and high

impedance. Other features include an internal precision

Rail-to-Rail

circuit that powers up the DAC in the 100kΩ power-down

mode.

The MAX5811 features a double-buffered I

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.
