Description

The TEA5761UK 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 tune to the European, US and Japanese FM bands. The radio does not meet all of the requirements of EN55020; a trade off has been implemented to achieve the following features.
