Notes:
1. The typical value of Rosc is 150 K for 8 MHz and 300 K for 4 MHz, and should be connected to GND (VSS).
2. Please refer to design guide to get typical Rosc value for each part number.
3. The Rs value is suggested in 270 ~ 1K to limit too large DAC output current flowing into transistor.
4. The capacitor, 4.7F, shunts between VDD and GND is necessary as power stability. But the value of
capacitor is depend on the application.
5. The above application circuit is for reference only. No warranty for mass production.
