Features  
Description  
The LTC®2637 is a family of octal 12-, 10-, and 8-bit  
voltage-output DACs with an integrated, high-accuracy,  
low-drift 10ppm/°C reference in 14-lead DFN and 16-lead  
MSOP packages. It has a rail-to-rail output buffer and is  
guaranteed monotonic. The LTC2637-L has a full-scale  
output of 2.5V, and operates from a single 2.7V to 5.5V  
supply. The LTC2637-H has a full-scale output of 4.096V,  
and operates from a 4.5V to 5.5V supply. Each DAC can  
also operate with an external reference, which sets the  
DAC full-scale output to the external reference voltage.

Low Power: 100µA per DAC at 3V (LTC2637-L)  
These DACs communicate via a 2-wire I2C-compatible  
serial interface. The LTC2637 operates in both the stan-  
dard mode (clock rate of 100kHz) and the fast mode (clock  
rate of 400kHz). The LTC2637 incorporates a power-on  
reset circuit. Options are available for reset to zero-scale  
or reset to mid-scale in internal reference mode, or reset  
to mid-scale in external reference mode after power-up.
