Sink/Source,Input/Output Current DAC Margining DS4424

Four Channel I2C Programmable Current DAC, 7 bit resolution. Input/Output DAC. Current margining


The DS4424 Current DAC IC contains four I2C programmable current DACs that are each capable of sinking or sourcing current up to 200μA. Each DAC output has 127 sink and 127 source settings that are programmed using the I2C interface. The current driven DAC outputs power up in a high-impedance state. The device is typically used for power supply margining, for DAC controlled current sources or for maintaining a constant current source.
