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.
