Arduino and ESP32 Compatibility
The TDA2822M can be integrated into Arduino and ESP32 audio projects using a suitable analog audio signal.
Arduino:
- Use an external DAC or a properly filtered PWM audio output.
- Connect the analog audio signal to the amplifier input through the appropriate external circuit.
- Use a suitable power supply and speaker.
ESP32:
- Use an external I2S DAC or another suitable analog audio source.
- Connect the analog signal to the amplifier input.
- Ensure proper grounding and power supply connections.
Note: The TDA2822M is an analog amplifier IC and does not directly support I2C, SPI, or UART communication.

Important Notes
-
This product is an integrated circuit (IC), not a complete amplifier module.
- Additional electronic components are required to build a functional amplifier.
- Output power depends on the supply voltage, speaker impedance, and circuit configuration.
- Do not exceed the manufacturer's recommended operating voltage.
- Use the appropriate application circuit for stereo or bridged operation.
- Check IC orientation and pin connections before applying power.
- The TDA2822M amplifies analog audio signals and does not decode digital audio.
