I'm trying to work with STAPI003 audio amplifier, in the datasheet it says that it 4 x 52 W/4 Ω max, but i am not able to get more than 32 watt at 4 ohm. How can i achieve above 32 watt, is it possible to bridge the output?

• 4 x 52 W/4 Ω max.
• 4 x 30 W/4 Ω @ 14.4 V, 1 kHz, 10 %

How is your Vcc ? For more power you need more Vcc...

Hello,

My Vcc is accurate 14.4V DC with 30amp available current. The supply voltage is not dropping when try to increase the sine wave source input, when the output goes above 32 watt it start clipping. So the maximum stable output i could reach at 4 ohm was 32 watt. Is there any trick for this IC to increase the output level?

I can only repeat trick is more Vcc see docu for max.

How about bridging the outputs, can this IC support this feature?
