Stereo/dual TV sound decoder circuit
Product specification
TDA3803A
GENERAL DESCRIPTION
The TDA3803A is a stereo/dual TV sound decoder circuit with static switching for processing two AF signals in TV and
VCR equipment. The LOW/HIGH static switching signals control the AF output selector. Two operational amplifiers
perform 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.)
