DESCRIPTION  
The LTC®2641/LTC2642 are families of 16-, 14- and 12-bit  
unbufferedvoltageoutputDACs.TheseDACsoperatefrom

temperature. UnbufferedDACoutputsresultinlowsupply  
current of 120μA and a low offset error of 1LꢀS.

ꢀchmitt-Trigger ꢁnputs for Direct Optocoupler  
The LTC2641/LTC2642 use a simple ꢀPꢁ/MꢁCROWꢁRE  
compatible 3-wire serial interface which can be operated  
at clock rates up to 50MHz and can interface directly  
with optocouplers for applications requiring isolation. A  
power-on reset circuit clears the LTC2641’s DAC output  
to zero scale and the LTC2642’s DAC output to midscale  
when power is initially applied. A logic low on the CLR pin  
asynchronously clears the DAC to zero scale (LTC2641N  
or midscale (LTC2642N. These DACs are all specified over  
the commercial and industrial ranges.
