General Description
The DS4412 contains two I2C adjustable-current DACs that are each capable of sinking or sourcing current. Each output has 15 sink and 15 source settings that are programmed by I2C interface. The full-scale range and step size of each output is determined by an external resistor that can adjust the output current over a 4:1 range.
The output pins, OUT0 and OUT1, power-up in a high impedance state.
