TBA440P

APLESSEY W Semiconductors. TBA440N / TBA440P TBA440N/P 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.
