ADVANCED MEDIUM VOLTAGE AM STEREO DECODER

The MC13022A is designed for home and automotive AM stereo radio applications. The circuits and functions included in the design allow implementation of a full–featured C–QUAMAM stereo radio with relatively few, inexpensive external parts. It is available in either 28–lead DIP or EIAJ compatible wide–bodied 28–lead SOIC. Functionally, the MC13022A and MC13022 are very similar. The MC13022A has 10 dB more audio output and a CMOS compatible logic level output (Pin 15) for stop sense. The stop sense/AGC function has been internally connected to the output notch filter control.
