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...
