Description
The DS4422 and DS4424 contain two or four I²C programmable current DACs that are each capable of sinking and sourcing current up to 200μA. Each DAC output has 127 sink and 127 source settings that are programmed using the I²C interface. The current DAC outputs power up in a high-impedance state.
