Dear Technical Support Team,
Could you see attached file?
I have some problem and questions.
1.)
I see the left shift of top of half sine wave by depending on increasing IDRIVE.
Does the shortage of drive capability causes this behavior?
I guess that expected top should be center of half sine wave.
2.)
Unbalanced half sine wave between INA and INB.
Should I add more capacitor on INB to keep balance both?
The both half sine waves should be same behavior(the difference is just phase shift of 180 degree )
3.)
To gain the altitude of sine wave, should I adjust the value of LC tank?
Current value:C=33pF、L＝18uH
