Notes:
1. The typical value of Rosc is 150 KΩ for 8MHz and 300 KΩ for 4MHz and should be connected to GND (VSS).
2. Please refer to design guide to get typical Rosc value for each part number.
3. In PCB layout, VSS1_SPK, VSS2_SPK should be connected to VSS; VDD1_SPK should be connected to VDD.
4. The Rs value is suggested in 270Ω ~ 1KΩ to limit too large DAC output current flowing into transistor.
5. The capacitor, 0.1uF, shunts between VDD and GND is necessary to filter power noise.
6. The capacitor, 4.7uF, shunts between VDD and GND is optional as power stability.
7. The 10Ω that between VDD and GND is to limit huge current flow into chip as driving too heavy loading.
8. The above application circuits are for reference only. No warranty for mass production.
