FEATURES  
DESCRIPTION  
The LTC®2654 is a family of quad 16-/12-bit rail-to-rail  
DACswithintegrated10ppm/°Cmaximumreference. The  
DACs have built-in high performance, rail-to-rail, output  
buffers and are guaranteed monotonic. The LTC2654-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 LTC2654-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.
