MAX5842 Datasheet (Maxim) - Quad / 12-Bit / Low-Power / 2-Wire / Serial Voltage-Output DAC

MAX5842, Quad / 12-Bit / Low-Power / 2-Wire / Serial Voltage-Output DAC

The MAX5842 is a quad, 12-bit voltage-output, digitalto-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 and draws only 230µA at VDD = 3.6V.

A powerdown mode decreases current consumption

MAX5842 Features

* 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. The MAX5842 features a double-buffered I2C-compatible
