DS4412
Dual-Channel, I²C Adjustable Sink/Source Current DAC
Inexpensive Power Supply Control Made Easy
|
Status
Active: In Production.
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.
