Product Summary

The TEA5764HN/N2 is a single chip electronically tuned FM stereo radio with Radio Data System (RDS) and Radio Broadcast Data System (RBDS) demodulator and RDS/RBDS decoder for portable application with fully integrated IF selectivity and demodulation. The radio is completely adjustment free and only requires a minimum of small and low cost external components. The radio can tune to the European, US and Japanese FM bands. It has a low power consumption and can operate at a low supply voltage.
