D01AU1319
balance (Left/Right) processor for quality audio appli-
cations in Hi-Fi systems.
Selectable input gain is provided. Control of all the
functions is accomplished by serial bus.
The AC signal setting is obtained by resistor net-
works and switches combined with operational ampli-
fiers.
Thanks to the used BIPOLAR/CMOS Technology,
Low Distortion, Low Noise and DC stepping are ob-
tained.

... I C BUS INTERFACE Data transmission from microprocessor to the TDA7443D and vice versa takes place through the 2 wires I interface, consisting of the two lines SDA and SCL (pull-up resistors to positive supply voltage must be connected). Data Validity As shown in fig. 1, the data on the SDA line must be stable during the high period of the clock. The HIGH and LOW state of the data line can only change when the clock signal on the SCL line is LOW ...
