Curtis,
We also have a 2kV ESD version, LM324K, LM2902K and LM2902KAV device that have ESD added to the input pins. All other versions only have their natural protection meaning that there are no ESD specific cells in the design. There is also the fallback…
Part Number: LM324A Other Parts Discussed in Thread: LM324 , LM2902K , LM324K , LM358 Hi Support team
May I know the Vf of Internal clamping diode
thank you
Hirokazu, Just like the LM324 and LM324K (and LM324A and LM324KA) share the same EC table data. LM2902 and LM2902K will also share the same EC table data. I will add this to next LM2902 data sheet update.
