Other Parts Discussed in Thread: TS321, , LM324A, LM258
Dear sir,
Customer wants to check whether there are ESD cell protection from Positive input (IN+) / Negative Input (IN-) to the power supply (V+/V-) inside?
AMP list:
LM258ADGKR
TS321IDBVR
If not,
Q1: how to explain LM258A/TS321 can pass the HBM/CDM ESD test?
Q2: If the input voltage of LM258A/TS321 is over the power supply, usually we add one resistor in serial to limit the current less than 10mA. and now no ESD cell at IN+/IN- to VCC & GND, how to do the over-voltage protection? Just add external diodes to GND/VCC?
Regards,
Jack
