Dual, 10-Bit, Low-Power, 2-Wire, Serial  
Voltage-Output DAC  
General Description  
Features  
The MAX5821 is a dual, 10-bit voltage-output, digital-to-  
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  
o Ultra-Low Supply Current  
115µA at V  
135µA at V  
= 3.6V  
= 5.5V  
DD  
DD  
o 300nA Low-Power Power-Down Mode  
o Single 2.7V to 5.5V Supply Voltage  
supply 115µA at V  
= 3.6V. A power-down mode  
DD  
decreases current consumption to less than 1µA. The  
MAX5821 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.  
o Fast 400kHz I2C-Compatible 2-Wire  
Serial Interface  
o Schmitt-Trigger Inputs for Direct Interfacing  
to Optocouplers  
o Rail-to-Rail Output Buffer Amplifiers  
The MAX5821 features a double-buffered I2C-compati-  
ble serial interface that allows multiple devices to share  
a single bus. All logic inputs are CMOS-logic compati-  
ble and buffered with Schmitt triggers, allowing direct  
interfacing to optocoupled and transformer-isolated  
interfaces. The MAX5821 minimizes digital noise  
feedthrough by disconnecting the clock (SCL) signal  
from the rest of the device when an address mismatch  
is detected.  
o Three Software-Selectable Power-Down Output  
Impedances  
100kΩ, 1kΩ, and High Impedance  
o Read-Back Mode for Bus and Data Checking  
o Power-On Reset to Zero  
o 8-Pin µMAX Package  
The MAX5821 is specified over the extended tempera-  
ture range of -40°C to +85°C and is available in a  
miniature 8-pin µMAX package. Refer to the MAX5822  
data sheet for the 12-bit version.
