Notes:

4.
5.
For W567B030~B260, VSSOSC should be connected to VSS; VDDOSC should be connected to VDD in PCB layout.
The Rs value is suggested in 270 ~ 1K to limit too large DAC output current flowing into transistor.
The 10 and 0.1uF between VDD, VDDOSC and GND are optional to filter power noise.
The capacitor, 4.7uF, shunts between VDD and GND is necessary as power stability. But the value of capacitor is
depend on the application.
The above application circuit is for reference only. No warranty for mass production.
