TDA3803A Overview
TDA3803A 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.
TDA3803A Key Features
- Amplification of the two AF input signals by integrated operational amplifiers
- Low distortion stereo de-matrix
- All operational amplifiers offset pensated
- 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 p
