Stereo/dual TV sound decoder circuit

INTEGRATED CIRCUITS DATA SHEET TDA3803A Stereo/dual TV sound decoder circuit Product specification File under Integrated Circuits, IC02 November 1987 Philips Semiconductors Product specification Stereo/dual TV sound decoder circuit GENERAL DESCRIPTION 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. 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.) QUICK REFERENCE DATA Supply voltage (pin 13) Supply current (pin 13) Pilot carrier amplifier gain control range A.F. input signals; at Gv = 0 dB (r.m.s. value) LED output current Weighted signal-to-noise ratio of the a.f. signal switches (CCIR468/2) Crosstalk in stereo mode Crosstalk in dual soun.
