TDA7476
s To use the TDA7476 with a car-radio system which has less than five audio channel and less than two
auxiliary loads, it is necessary to take some cares:
- each pin CH± not used has to be fixed to 5V
- each pin AUX1IN, AUX1OUT, AUXIN2, AUX2OUT not used has to be fixed to a voltage equal or greater than 5V
The 5V voltage reference available on the chip (pin 10) is very useful to fix both CH± and AUX pins to
5V.
