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.
