DAC7612  
Dual, 12-Bit Serial Input  
DIGITAL-TO-ANALOG CONVERTER  
DESCRIPTION  
FEATURES  
The DAC7612 is a dual, 12-bit digital-to-analog con-  
verter (DAC) with guaranteed 12-bit monotonicity  
performance over the industrial temperature range. It  
requires a single +5V supply and contains an input  
shift register, latch, 2.435V reference, a dual DAC, and  
high speed rail-to-rail output amplifiers. For a full-  
scale step, each output will settle to 1 LSB within 7µs  
while only consuming 3.7mW.  
LOW POWER: 3.7mW  
FAST SETTLING: 7µs to 1 LSB  
1mV LSB WITH 4.095V FULL-SCALE  
RANGE  
COMPLETE WITH REFERENCE  
12-BIT LINEARITY AND MONOTONICITY  
OVER INDUSTRIAL TEMP RANGE  
The synchronous serial interface is compatible with a  
wide variety of DSPs and microcontrollers. Clock  
(CLK), Serial Data In (SDI), Chip Select (CS) and  
Load DACs (LOADDACS) comprise the serial inter-  
face.  
3-WIRE INTERFACE: Up to 20MHz Clock  
SMALL PACKAGE: 8-Lead SOIC  
APPLICATIONS  
PROCESS CONTROL  
The DAC7612 is available in an 8-lead SOIC package  
and is fully specified over the industrial temperature  
range of –40°C to +85°C.
