VIDEO IF AMPLIFIER DEMODULATOR
The TBA440 (TBA440N for NPN tuners, TBA440P for
PNP tuners) comprises a high-gain regulated video IF
amplifier, a controlled demodulator andtwo low-resistance
video outputs w i t h positive and negative signal as well as
the complete key control and delayed tuner control.
