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● Eight (TDA2555) or five (TDA2557) stage limiting amplifier
● Quadrature demodulator for FM detection
● De-emphasis stage
● Output amplifier
● Mute function for each FM demodulator QUICK REFERENCE DATA Supply voltage (pins 13 and 15) Supply current (pins 13 and 15) AF output voltage (pins 2 and 8) Total harmonic distortion (note 1) Signal to weighted noise ratio PACKAGE OUTLINE 18-lead DIL; plastic (SOT102); SOT102-1; 1996 November 19.
