TDA7404D
16/26
The External AC - Coupling is selected in position of four switches controlled by the lower 2bit in the Others
selection. (See table)
Others selection
1.10Speaker Attenuator
Due to practical aspects the steps in the speaker-attenuators are not linear over the full range. At attenuations
more than 24dB the steps increase from 1.5dB to 10dB (please see data byte specification).
1.11Subwoofer Attenuator
The Subwoofer output is a single ended stereo output. The attenuator is exactly the same like the other speak-
ers.

C BUS INTERFACE
2.1 Interface Protocol
The interface protocol comprises:
I
a start condition (S)
I
a chip address byte (the LSB bit determines read / write transmission)
I
a subaddress byte
I
a sequence of data (N-bytes + acknowledge)
I
a stop condition (P)
I
the max. CLOCK SPEED is 500kbits/s
S = Start
R/W ="0" -> Receive-Mode (Chip could be programmed by P)
"1" -> Transmission-Mode (Data could be received by P)
ACK = Acknowledge
P = Stop
2.2 TRANSMITTED DATA (send mode)
SM = Soft mute activated
X = Not Used
The transmitted data is automatic updated after each ACK. Transmission can be repeated without new chipaddress.
