MAX5822 Datasheet Dual / 12-bit / Low-power / 2-wire / Serial Voltage-output Dac

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-2315; Rev 0; 1/02 Dual, 12-Bit, Low-Power, 2-Wire, Serial Voltage-Output.

General Description

The MAX5822 is a dual, 12-bit, voltage-output, digital-toanalog converter (DAC) with an I2C™-patible, 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 115µA at VDD = 3.6V.

A power-down mode decreases current consumption to less than 1µA.

Key Features

  • three software-selectable powerdown 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. The MAX5822 features a double-buffered I2C-compatible serial interface that allows multiple devices to share a single bus. All logic inputs are CMOS-logic compatible and buffered with Schmitt triggers, allowing direct interfacing to optocoupled and trans.
