Other Parts Discussed in Thread: TPA3136D2
I had one last question about the single ended p-p voltage measured across
the resistive load.The load is 4 Ohm, 3W. The max p-p voltage across the
load should ideally be 9.78 V. This translates to max Vin p-p = 0.49V for this
class D amplifier.
I tried Plimit = 1.25 V and Plimit = 2V (both scope waveforms attached). There is
barely any difference in the output p-p voltage. It falls short of the ideal max by 1V p-p.
What are likely causes? How can this be improved?
Edited to add: DC power supply to the EVM is 12V.
Thank you,
Priya
PLIMIT = 1.25V
PLIMIT = 2V
