Sound fader control circuit

TEA6300

TEA6300T

circuit. Signal-to-noise ratios exclude noise contribution of the power amplifier.

2. Signal-to-noise ratios on a CCIR 468-2 average meter reading are 4,5 dB better than on CCIR 468-2 quasi peak.

If more than 1 byte of DATA is transmitted, then auto-increment of the subaddress is performed.
