DAC9881 bipolar output typical application circuit

Supply 1206 red and green two-color 1210 red and green two-color LED light-emitting diode

DAC9881 is a high-performance digital-to-analog converter chip with serial input, parallel processing and voltage output. It has high precision and fast speed, which can greatly reduce the occupation of data bus. It is widely used in high-precision control occasions. And waveform generation circuit. As shown in the figure, when RA=2RB=2RC, VO=4VOUT-2VREF, which can form a bipolar voltage signal with an output of -2VREF~+2VREF.
