The typical value of Rosc is 160 KΩ for 8MHz and 330 KΩ for 4MHz and should be connected to GND (VSS).

Please refer to design guide to get typical Rosc value for each part number.

The Rs value is suggested in 270Ω ~ 1KΩ to limit too large DAC output current flowing into transistor.

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 circuits are for reference only. No warranty for mass production.
