Maximum INL Error: ±±LꢀS at 1ꢁ Sitꢂ  
Rail DACs with integrated 10ppm/°C max reference. The  
DACs have built-in high performance, rail-to-rail, output  
buffers and are guaranteed monotonic. The LTC2655-L  
has a full-scale output of 2.5V with the integrated refer-  
ence and operates from a single 2.7V to 5.5V supply.  
The LTC2655-H has a full-scale output of 4.096V with  
the integrated reference and operates from a 4.5V to  
5.5V supply. Each DAC can also operate with an external  
reference, which sets the full-scale output to 2 times the  
external reference voltage.

The parts use the 2-wire I C compatible serial interface.  
The LTC2655 operates in both the standard mode (maxi-  
mum clock rate of 100kHz) and the fast mode (maximum  
clock rate of 400kHz). The LTC2655 incorporates a  
power-on reset circuit that is controlled by the PORSEL  
pin. If PORSEL is tied to GND the DACs power-on reset to
