DS4412
DS4412 is I2C Adjustable Sink/Source Current DAC manufactured by Maxim Integrated.
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 highimpedance state.
