Dual TV sound demodulator circuits
GENERAL DESCRIPTION
TDA2555 TDA2557
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.
• Eight (TDA2555) or five (TDA2557) stage limiting amplifier • Quadrature demodulator for FM detection • De-emphasis stage • Output amplifier • Mute function for ea...
