VCC12

In applications where a 12 volt supply from slow blanking is used to

derive the internal audio 9 Volt supply voltage, the VCCAO pin must be

connected to the 12 volt supply as shown in the example. The VCCA

pin will show the regulated 9 volt audio supply voltage which must be

decoupled by capacitors.

In applications having a dedicated audio supply voltage, the VCCAO

pin must be connected together with the VCCA pin to the audio supply

as shown in the example. The VCCA pin acts as power supply input

for the internal audio block.
