LM7171: Input structure

Part Number: LM7171

For this device, I assume there are input protection diodes to positive and from negative supply.

Any additional considerations to guard against latchup event?

Should I also limit input current? It isn't clear from datasheet.

Thanks.

Hello Gregory,

There should not be a latchup event during normal operating conditions specified in the datasheet. Would you be attempting to protect the device against EOS or power supply overvoltage condition where specifications would go above the absolute maximum ratings of the amplifier?

Thank you,

Sima

Hi Sima,

what do you mean by "EOS"?
