Part Number: LMV225
Hi,Customers designed products using LMV 225. However, the product can not pass the shipping test at a frequency of 5%.It is due to output malfunction of LMV225.If they replace the LMV 225 with the same circuit board, the product will pass the test.
Questions, - This output malfunction is genraly? - Please tell me know how often this symptom occurs. - Please tell me know solution for it.Regards,ACGUY
I obtained a correlation waveform between RFin and VOUT. Please look the attached new file.
RFin rises vertically, but Vout is tilted.
Please tell me the cause and solution.

Hi VC-san,I obtained the input condition from customer.On the NG board that PA output ricochet to rise, then it becomes normal.When the resistance value of R1 is lowered, will the output of LMV 225 be improved?Regards,ACGUY
Thank you, we are working to get you a response as soon as possible. Apologies for the delay, thanks for the patience
