MAX5812 Datasheet PDF (12-Bit Low-Power / 2-Wire / Serial Voltage-Output DAC)

MAX5812 - 12-Bit Low-Power / 2-Wire / Serial Voltage-Output DAC

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.

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.

19-2340; Rev 0; 1/02 12-Bit Low-Power, 2-Wire, Serial Voltage-Output DAC 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. The MAX5812 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.
