Overview

19-4541; Rev 0; 4/09 com Quad-Channel, I2C-Margining IDACs with Three Channels of Power-Supply Tracking General Description The DS4426 contains four I2C-adjustable current DACs capable of sinking or sourcing current.
External resistors set the full-scale range of each output.
Each DAC output has 127 sink and 127 source steps that are programmed by the I2C interface.
Power-supply tracking functionality is provided for three channels using dedicated 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 on the same I2C bus.
Features ♦ Four Current DACs 50µA to 200µA Adjustable...
