Instructions
Power Supply Connection:
- Connect the positive terminal of the power supply to Vcc (pin 8).
- Connect the negative terminal of the power supply to GND (pin 4).
Input Signal Connection:
- Connect the audio input signal to IN+ (pin 2).
- Connect the ground of the input signal to GND (pin 4).
Speaker Connection:
- Connect the positive terminal of the speaker to OUT (pin 6).
- Connect the negative terminal of the speaker to GND (pin 4).
Decoupling Capacitors:
- Place a 10μF electrolytic capacitor between Vcc and GND close to the IC to stabilize the power supply.
- Optionally, place a 0.1μF ceramic capacitor between Vcc and GND for high-frequency noise suppression.
Output Coupling Capacitor:
- Use a 100μF electrolytic capacitor in series with the speaker to block any DC component from the output.
Heat Dissipation:
- Ensure adequate heat dissipation if operating at high power levels or in high ambient temperatures. Consider using a heatsink if necessary.
Protection:
- Avoid short circuits and ensure all connections are secure to prevent damage to the IC.
Testing:
- Apply a small audio signal to the input and verify the output on the speaker. Adjust the volume as needed.
Storage:
- Store the IC in a dry, cool place to avoid moisture damage.
