TPA3121D2: Gain db is less TPA3121D2

Part Number: TPA3121D2

Hi Shawn,

While testing audio power amplifier TPA3121D2 , i find gain is 4db than what is set through gain resistors. 

As per datasheet , tolerance is of +-2db only. I give 24V input , i find clipping at output more than 7V.

When connecting load 8ohm , amplifier shuts down output.

Is this related to supply pumping.?

Please guide me to sort out this.

Thanks,

Divy
