12-Bit Low-Power, 2-Wire, Serial  
Voltage-Output DAC  
General Description  
Features  
The MAX5812 is a single, 12-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 supply and  
o Ultra-Low Supply Current  
100µA at V  
130µA at V  
= 3.6V  
= 5.5V  
DD  
DD  
o 300nA Low-Power Power-Down Mode  
o Single 2.7V to 5.5V Supply Voltage  
draws only 100µA at V  
= 3.6V. A low-power power-  
DD  
down 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  
o Fast 400kHz I2C-Compatible 2-Wire Serial  
Interface  
®
Rail-to-Rail output buffer and a power-on reset circuit  
o Schmitt-Trigger Inputs for Direct Interfacing to  
that powers up the DAC in the 100kΩ power-down mode.  
Optocouplers  
The MAX5812 features a double-buffered I2C-compatible  
serial interface that allows multiple devices to share a sin-  
gle bus. All logic inputs are CMOS-logic compatible and  
buffered with Schmitt triggers, allowing direct interfacing  
to optocoupled and transformer-isolated interfaces. The  
MAX5812 minimizes digital noise feedthrough by discon-  
necting the clock (SCL) signal from the rest of the device  
when an address mismatch is detected.  
o Rail-to-Rail Output Buffer Amplifier  
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  
The MAX5812 is specified over the extended temperature  
range of -40°C to +85°C and is available in a space-sav-  
ing 6-pin SOT23 package. Refer to the MAX5811 for the  
10-bit version.
