This article describes the FM Radio Receiver for Battery Supply (TDA7088T). The principle is very simple, very practical. The circuit components can help you understand better grasp this principle. For example, in this circuit, you can go to find and buy these components: TDA7088T.

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:


FM Radio Receiver for Battery Supply circuit schematic


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]
