com Rev 0; 9/07 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 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.
Features ♦ Two Current DACs ♦ Full-Scale Current 500µA to 2mA ♦ Full-Scale Range for Each DAC Determined by External Resistors ♦ 15 Settings Each for Sink and Source Modes ♦ I2C-Compatible Serial Interface ♦ Low Cost ♦ Small Package (8-Pin µSOP) ♦ -40°C to +85°C Temperature Range ♦ 2.
