Dual, 8-Bit, Low-Power, 2-Wire, Serial

Voltage-Output DAC

General Description

Features

The MAX5820 is a dual, 8-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

♦ Ultra-Low Supply Current

115µA at V

135µA at V

= 3.6V

= 5.5V

♦ 300nA Low-Power Power-Down Mode

(115µA at V

= 3.6V). A power-down mode decreases

♦ Single 2.7V to 5.5V Supply Voltage

♦ Fast 400kHz I²C-Compatible 2-Wire

current consumption to less than 1µA. The MAX5820 fea-

tures three software-selectable power-down output

impedances: 100kΩ, 1kΩ, and high impedance. Other

features include internal precision rail-to-rail output

buffers and a power-on reset (POR) circuit that powers up

the DAC in the 100kΩ power-down mode.

Serial Interface

♦ Schmitt-Trigger Inputs for Direct Interfacing

to Optocouplers

The MAX5820 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

MAX5820 minimizes digital noise feedthrough by discon-

necting the clock (SCL) signal from the rest of the device

when an address mismatch is detected.

♦ Rail-to-Rail Output Buffer Amplifiers

♦ Three Software-Selectable Power-Down Output

Impedances

100kΩ, 1kΩ, and High Impedance

♦ Readback Mode for Bus and Data Checking

♦ Power-On Reset to Zero

♦ 8-Pin µMAX Package

The MAX5820 is specified over the extended (-40°C to

+85°C) temperature range and is available in a small

Ordering Information

8-pin µMAX package. Refer to the MAX5822 data

sheet for the 12-bit version and to the MAX5821 data

sheet for a 10-bit version.
