Class T Audio Amplifiers

Hi i have 3020v4 board.

What is your voltage for fan?

I have misured 2,24 V DC

Is normally? The fan goes slowly....

[Cristi]

yes is normal, the voltage is temperature dependent. when the power amplifer heatsink will get hot the fan voltage will be higher and fan will spin faster. when the temperature will drop the voltage will drop too. the fan starts to spin at about 4.5V

I intended to develop another controller board, DSP based. Time is not on my side in the past few months, so i cannot say when will be available, of course if will be interest i can put it on the priority list.

HI,
I have TA3020 Audio Amplifier v3c and I would like to buy this module for the vers.V3C if it is compatible can you ship me it.
Have a good day

TA3020v3d uses a dedicated 16 pins connector to connect the small control board with the main board. all the signal power and supply lines are routed through and is very difficult to adapt this to other module such as TA3020v3c.
