Instructions for TDA2616/N1+112

1. Power Supply Connection:

   • Connect the positive terminal of the power supply to pin 8 (Vcc) and the negative terminal to pin 4 (GND).

2. Input Connection:

   • Connect the audio input signal to pins 2 (IN-) and 3 (IN+). Ensure the input signal level does not exceed the specified input sensitivity to avoid distortion.

3. Output Configuration:

   • Connect an 8Ω speaker or equivalent load between pins 5 (OUT) and pin 4 (GND). Do not connect loads with lower impedance as it can damage the IC.

4. Capacitors:

   • Place a 10μF electrolytic capacitor between Vcc and GND close to the IC for power supply decoupling.
   • Use a 0.1μF ceramic capacitor between Vcc and GND for high-frequency noise suppression.

5. Shutdown Mode:

   • To put the IC into shutdown mode, pull pin 6 (SD) low. The shutdown current will be reduced to the specified value.

6. Thermal Considerations:

   • Ensure adequate heat dissipation if operating at maximum power levels. Mounting the IC on a heatsink may be necessary for continuous operation.

7. Protection Circuits:

   • The IC includes built-in protection circuits for short circuit, overtemperature, and thermal shutdown. However, proper PCB layout and component selection are still important for reliable operation.

8. Layout Guidelines:

   • Keep signal paths as short as possible to minimize noise pickup.
   • Ensure good grounding practices by using a ground plane and minimizing ground loops.
