Instructions for TEA0652

1. Power Supply Connection:

   • Connect the positive terminal of the power supply to the VDD pin.
   • Connect the negative terminal of the power supply to the GND pin.

2. Input Signal Connection:

   • Connect your audio source to the input pins (IN+ and IN-).
   • Ensure the input signal level is appropriate for optimal performance.

3. Output Configuration:

   • Connect the speaker or load to the OUT+ and OUT- terminals.
   • Verify that the impedance of the speaker matches the recommended load impedance for this device.

4. Shutdown Mode:

   • To put the device into shutdown mode, apply a low logic level to the SD pin.
   • In shutdown mode, the current consumption drops significantly to minimize power usage.

5. Heat Dissipation:

   • Ensure adequate heat dissipation by mounting the IC on a heatsink if necessary, especially when operating at higher power levels.

6. Protection Circuits:

   • The TEA0652 includes built-in protection against short circuits and thermal overload. No additional components are required for these protections.

7. Layout Considerations:

   • Keep the layout compact and minimize trace lengths, especially for power and ground connections, to reduce noise and improve stability.
