MAX5821 Datasheet (Maxim) - Dual / 10-Bit / Low-Power / 2-Wire / Serial Voltage-Output DAC

MAX5821, Dual / 10-Bit / Low-Power / 2-Wire / Serial Voltage-Output DAC

The MAX5821 is a dual, 10-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 V DD = 3.6V.

A power-down mode decreases current consumption to less

MAX5821 Features

* three software-selectable powerdown output impedances: 100k Ω , 1k Ω , 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 powerdown mode. The MAX5821 features a double-buffered I2C-compatib
