FM收音模組 TEA5767模組

1. General description

The TEA5767HN is a single-chip electronically tuned FM stereo radio for low-voltage

applications 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 be tuned to the European, US and Japanese FM bands.

2. Features
