STMicroelectronics recommends using a 10uF ceramic capacitor and a 100nF ceramic capacitor in parallel, placed as close as possible to the power supply pins (VCC and GND) to ensure proper decoupling and noise reduction.
The gain setting of the TDA7496SA depends on the input signal level and the desired output power. A good starting point is to set the gain to 20dB (default setting) and adjust it based on the input signal level and desired output power. The gain can be adjusted using the GAIN pin or through the I2C interface.
The TDA7496SA can handle a maximum power of 40W per channel into a 4Ω load, or 20W per channel into an 8Ω load. However, the actual power handling capability may vary depending on the application, PCB design, and thermal management.
Proper thermal management is crucial for the TDA7496SA. Ensure good airflow around the device, use a heat sink if necessary, and avoid blocking the thermal pads on the package. The device has a thermal shutdown feature that activates when the junction temperature exceeds 150°C.
Yes, the TDA7496SA can be used in a bridged configuration to increase the output power. However, this requires careful design and layout considerations to ensure proper operation and to avoid oscillations.
