General Description

The MAX5811 is a single, 10-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 MAX5811 features three software-selectable
power-down output impedances: 100k

Ω

, 1k

Ω

, 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 100k

Ω

power-down

mode.
The MAX5811 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
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.
