Sound control circuit

TEA6324T

Notes to the characteristics

1. The indicated values for output power assume a 6 W power amplifier at 4

Ω with 20 dB gain and a fixed attenuator

of 12 dB in front of it. Signal-to-noise ratios exclude noise contribution of the power amplifier.

2. The transmission contains: total initialization with MAD and subaddress for volume and 8 data words, see also

definition of characteristics, clock frequency = 50 kHz, repetition burst rate = 400 Hz, maximum bus signal

amplitude = 5 V (p-p).
