Description



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.)

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.
