Frequently asked questions

How can I verify the correct power supply?
Check the datasheet for the specified power supply voltage and use a multimeter to measure the applied voltage.

Why should I use a protection resistor?
The protection resistor safeguards your speakers from damage in case of overloading or short circuit.

Can I use a pair of headphones instead of speakers?
Yes, but make sure the headphone impedance is below 32 Ohm.

Does the TDA7498 support analog audio?
Check the datasheet to see if it supports analog inputs.
