Notes:

1.

The typical value of Rosc is 150 K

2.

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

3.

4.

The Rs value is suggested in 270

Ω ~ 1KΩ to limit too large DAC output current flowing into transistor.

5.

The 10

6.

The capacitor, 4.7

depend on the application.
