The AN7222 is designed as one kind of frequency modulation & amplitude modulation power amplifier integrated circuit that can be used in all kinds of audio system radio circuits such as the home audio and car audio systems. 1.Features The AN7222 has the AM detection and FM detection circuits, both of them have the level driver circuit; it has the automatic frequency control function, because of the AM high frequency amplifier, the sensitivity is good, the power consumption is low, and the external components are few. The internal circuit block diagram is as shown in figure. Figure 1 The internal circuit block diagram of AN7222 2.Pin functions and data The AN7222 uses the 18-pin dual-row DIP package, the pin functions and data are as shown in table 1. Table 1 The pin functions and data of the AN7222 3.The typical application circuit of the AN7222
