FM Radio Receiver for Battery Supply

The TDA7088T can be used in mono portable and pocket radios. This is a bipolar integrated circuit. Here’s one of the application circuit diagram:

When a minimum of peripheral components (of small dimensions and low cost) is important, we can use TDA7088T. Frequency-locked -loop (FLL) system with an Intermediate Frequency (IF) of about 70 KHz is built on this circuit. By active RC-filters, selectivity is achieved.De-tunning related to the IF and the mute circuit is suppress too week input signals. [Source: NXP Application Note]
