The TEA5710 AM-FM radio IC is obsolete and is not made anymore. It cannot drive a speaker, it is designed to drive an amplifier that drives speakers or headphones.

Audioguru so what are the best AM/FM receiver Radio ICs that are commonly stocked on many local markets.
I need to use in my project but sourcing these is a big challenge in my community.
Most vendors don't have radio ICs.They possess plenty of invertors, amplifiers ICs

Good radio ICs are tiny and they are digital so you need a computer to program them. Google found the SI4825. It is available at Digikey. I do not know if it is any good.
