TPA3111D1: 5W instead of 10W output power

Part Number: TPA3111D1

Hello

We are using TPA3111D1, but we don´t get 10 watts on the output. Nevertheless, the datasheet say "10-W into an 8-Ω Load at 10% THD+N From a 12-V Supply"

The maximum power we get are 5 watts.

In the input we have a sinusoidal signal of 1kHz / 680mVrms

If we raise the signal level at the input, the output signal is deformed.

We have set the gain in 20dB and we are using a resistor of 8Ω as a load.

The power supply is 12Vdc.

We have the PLIMIT input connected to the GVDD output in order to avoid power limitation.

You can see below our schematic

 

thanks
