MAX5812 Datasheet 12-bit Low-power / 2-wire / Serial Voltage-output Dac

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-2340; Rev 0; 1/02 12-Bit Low-Power, 2-Wire, Serial Voltage-Output.

General Description

The MAX5812 is a single, 12-bit voltage-output, digital-toanalog 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 draws only 100µA at VDD = 3.6V.

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

Key Features

  • three software-selectable power-down output impedances: 100kΩ, 1kΩ, and high impedance. Other features include an internal precision Rail-to-Rail® output buffer and a power-on reset circuit that powers up the DAC in the 100kΩ power-down mode. The MAX5812 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 transfor.
