Other Parts Discussed in Thread: TINA-TI
Hi,
My customer is using the TPA6211A1.
Some samples has large gain error in comparison to normal one.
Its abnormal gain is larger than simulation result by TINA-TI, so I suspect spec out.
Please refer the attached files.
TPA6211A.xlsx TPA6211A sim.TSC
Appearing probabillity of abnormal sample is about 1%.
This is caused by not boards but samples, we checked by swapping IC.
Could you investigate about this defect?
Best Regards,
Kuramochi
