Dual-Channel, I2C Adjustable
Sink/Source Current DAC
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 pro-
grammed 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.
