MAX5820 Serial Voltage-Output DAC

The MAX5820 is a dual, 8-bit voltage-output, digital-toanalog converter (DAC) with an I 2 C*-compatible, 2-wire interface that operates at clock rates up to 400kHz. The device operates from a single 2.7V to 5.5V supply (115µA at VDD = 3.6V). A power-down mode decreases current consumption to less than 1µA. The MAX5820 features three software-selectable power.

Features

three software-selectable power-down output impedances: 100kΩ, 1kΩ, and high impedance. Other www.DataSheet4U.com 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 MAX5820 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 transformer-isolated interfaces. The MAX5820 minimizes digital noise feedthrough by d.
