10-Bit, Low-Power, 2-Wire Interface, Serial,

Voltage-Output DAC

General Description

Features

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

ꢀ Ultra-Low Supply Current

100µA at V

130µA at V

= 3.6V

= 5.5V

ꢀ 300nA Low-Power Power-Down Mode

ꢀ Single 2.7V to 5.5V Supply Voltage

draws only 100µA at V

= 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: 100kΩ, 1kΩ, and high

impedance. Other features include an internal precision

ꢀ Fast 400kHz I²C-Compatible 2-Wire Serial

Interface

Rail-to-Rail output buffer and a power-on reset (POR)

ꢀ Schmitt-Trigger Inputs for Direct Interfacing

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

to Optocouplers

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.

100kΩ, 1kΩ, and High Impedance

ꢀ Read-Back Mode for Bus and Data Checking

ꢀ Power-On Reset to Zero

ꢀ Miniature 6-Pin SOT23 Package

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.
