Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage is within the specified range (11V to 26V).
   • Use a stable and well-regulated power supply to avoid distortion and potential damage.

2. Heat Dissipation:

   • Mount the TDA7379 on a heatsink to ensure proper heat dissipation, especially when operating at high power levels.
   • The heatsink should have sufficient surface area and thermal conductivity to maintain the device within its operating temperature range.

3. Input Connection:

   • Connect the input signals to the designated input pins. The input impedance is 47 kΩ, so ensure the source impedance is compatible.
   • Use shielded cables to minimize noise and interference.

4. Output Connection:

   • Connect the speaker loads to the output terminals. The TDA7379 can drive 8Ω or 4Ω speakers.
   • Ensure the speaker wires are of appropriate gauge to handle the current and minimize resistance.

5. Protection:

   • The TDA7379 includes built-in protection against overvoltage, overcurrent, and thermal overload. However, it is still important to avoid conditions that could trigger these protections, as they may affect performance.

6. Grounding:

   • Ensure proper grounding to prevent ground loops and reduce noise. Ground all components and the chassis to a common point.

7. Initial Testing:

   • Before connecting speakers, perform initial testing with a low-power signal to verify proper operation and check for any issues.
   • Gradually increase the input signal level while monitoring the output and temperature.

8. Storage and Handling:

   • Store the TDA7379 in a dry, cool place away from static electricity.
   • Handle the device with care to avoid physical damage and electrostatic discharge (ESD).

By following these instructions, you can ensure optimal performance and longevity of the TDA7379 audio amplifier.
