DESCRIPTION  
n
Integrated Precision Reference  
The LTC®2631 is a family of 12-, 10-, and 8-bit voltage-  
output DACs with an integrated, high accuracy, low-drift  
referenceinan8-leadTSOT-23package.Ithasarail-to-rail

Bidirectional Reference: Input or 10ppm/°C Output  
The LTC2631-L has a full-scale output of 2.5V, and oper-  
ates from a single 2.7V to 5.5V supply. The LTC2631-H  
hasafull-scaleoutputof4.096V, andoperatesfroma4.5V  
to 5.5V supply. A 10ppm/°C reference output is available  
at the REF pin.

Power-On Reset to Zero or Mid-Scale Options  
Double-Buffered Data Latches  
Each DAC can also operate in External Reference mode,  
in which a voltage supplied to the REF pin sets the full-  
scale output.

The LTC2631 DACs use a 2-wire, I C-compatible serial

interface. The LTC2631 operates in both the standard  
mode (clock rate of 100kHz) and the fast mode (clock  
rate of 400kHz).  
APPLICATIONS  
The LTC2631 incorporates a power-on reset circuit. Op-  
tions are available for reset to zero-scale or reset to mid-  
scale after power-up.
