TEA5766UK
General Description
The TEA5766UK 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 Intermediate Frequency (IF) selectivity and FM 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 at a low supply voltage.
The TEA5766UK application software is compatible to the TEA5764 software to enable easy design-in for customers.
