TDA2557 - Dual TV sound demodulator circuits

General Description

The circuits incorporate two FM demodulator systems to perform the demodulator functions required in a dual sound carrier TV system for demodulating the sound carriers.

The difference between TDA2555 and TDA2557 is the number of stages of the limiting amplifier.
