Notes to the characteristics
1. The indicated values for output power assume a 6 W power amplifier at 4
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).
3. The AC characteristics are in accordance with the I2C-bus specification. This specification,
“The I2C-bus and how to
use it”, can be ordered using the code 9398 393 40011.
