LM48100Q-Q1: Output Power of Audio Chip

user2013294

Part Number: LM48100Q-Q1

Hi,

We are using LM48100 to driver speaker. The HW design is attached as below.

The output power in LM48100's datasheet is 1.3W. We are trying to understand the output power is peak to peak output power(peak voltage of OUTA to peak voltage of OUTB), or it is RMS power?

Could someone help clarify this?

thanks,

John

Hi, John,

Excuse me, could you share your circuit schematic again, please? It seems that the file was not attached correctly to the e2e thread.

Best regards,

Hi,

The output power is defined by the output amplitude. Otherwise, it would be noted as Prms.
