Dear all:
According to datasheet Figure17, THD should be less than 1% when 2W output, but the measurement on evm is more than 6%.
Some of the frequencies even exceed 8.
On the other hand, I found that Gain is not flat, if the input voltage exceeds 0.45v, the output gain starts to decrease.
Test Conditions:
VDD=5v ,4ohm SPK, R2=R3=50Kohm(Gain=6)
Do you think this result is normal?
