Other Parts Discussed in Thread: LM4140
I am using LMP7721 for designing signal conditioning of pH probe.
I have taken sample of LMP7721 from TI (SMD packaging).
The problem with my LMP7721 is that it works fine for few days(hardly one or two day) and after that it goes into saturation (either positive or negative).
I am using LMP7721 as buffer for signal of pH probe.
I have tried at least 5-6 lmp7721 till now but not a single one is working. every lmp7721 gets into saturation.
What should I do?
Any precaution that need to be taken while handling lmp7721 (smd packging).
Please help me out!!!
