DS4412U+T&R
数模转换器- DAC 2 Ch I2C Adj Sink/Source Current
Dual-Channel, I2C Adjustable Sink/Source Current DAC
DS4412U+ 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.
DS4412U+ 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
♦ 2.7V to 5.5V Operation
