Quad-Channel, I C-Margining IDACs with  
Three Channels of Power-Supply Tracking  
DS426  
General Description  
Features  
2
The DS4426 contains four I C-adjustable current DACs  
Four Current DACs  
capable of sinking or sourcing current. External resis-  
tors set the full-scale range of each output. Each DAC  
output has 127 sink and 127 source steps that are pro-  
50µA to 200µA Adjustable Full-Scale Range  
127 Settings Each for Sink and Source  
2
Power-Supply Tracking  
grammed by the I C interface. Power-supply tracking  
functionality is provided for three channels using dedi-  
cated control inputs. Once power-supply tracking is  
accomplished, the current outputs default to zero. Two  
address pins allow up to four DS4426 devices to exist
