TDA3803A Stereo/dual TV sound decoder circuitThe TDA3803A is a stereo/dual TV sound decoder circuit with static switching for processing two AF signals in TV andVCR equipment. The LOW/HIGH static switching signals control the AF output selector. Two operational amplifiersperform bandpass filtering of the identification signals.Features· Amplification of the two AF input signals by integrated operational amplifiers· Low distortion stereo de-matrix· All operational amplifiers offset compensated· De-emphasis with operational amplifiers, preferably applied to the output terminals· Two output ports each with two channels for headphones and loudspeakers· Dual sound information at one port, each port individually switchable from sound I to sound II and sound II to sound I· Mute function; while mute is active, it is possible to connect an external mono AF input signal to pin 10 appearing at pins 20 to 23.· Identification without additional signals (horizontal etc.)
