Product specification
Television IF amplifier and demodulator
TDA8340
TDA8341
DESCRIPTION
The TDA8340;Q and TDA8341;Q are integrated IF
amplifier and demodulator circuits for colour or black/white
television receivers, the TDA8340;Q is for application with
n-p-n tuners and the TDA8341;Q for p-n-p tuners.
The TDA8340;Q and TDA8341;Q are pin-compatible
successors with improved performance to types
TDA2540/2541;Q and TDA3540/3541;Q.
Features
Full range gain-controlled wide-band IF amplifier
Linear synchronous demodulator with excellent
intermodulation performance
White spot inverter
Wide-band video amplifier with noise protection
AFC circuit with AFC on/off switching and
sample-and-hold function
Low impedance AFC output
AGC circuit with noise gating
Tuner AGC output for n-p-n tuners (TDA8340) or p-n-p
tuners (TDA8341)
External video switch for switching-off the video output
Reduced sensitivity for high sound carriers
Integrated filter to limit second harmonic IF signals
Wide supply voltage range
Requires few external components
