DACs with 10ppm/°C  
Max Reference  
FEATURES  
DESCRIPTION  
The LTC®2656 is a family of octal 16-/12-bit rail-to-rail  
DACs with a precision integrated reference. The DACs have  
built-in high performance, rail-to-rail, output buffers and  
are guaranteed monotonic. The LTC2656-L has a full-scale  
output of 2.5V with the integrated 10ppm/°C reference and  
operates from a single 2.7V to 5.5V supply. The LTC2656-H  
has a full-scale output of ±.096V with the integrated refer-  
enceandoperatesfroma±.5Vto5.5Vsupply.EachDACcan  
also operate with an external reference, which sets the DAC
