LMH6657: input current of absolute maximum ratings

Ryuji

Part Number: LMH6657

Hello,

Could you please let me know the meaning of input current +/-10mA in the table of absolute maximum ratings?
If the input current is used within 10 mA, is there no problem if the input voltage exceeds the absolute maximum rating ("V -" - 0.8 V, "V +" + 0.8 V)?

If no, please let me know the case where the input current exceeds +/-10mA.

    Hello Ryuji,

    The absolute maximum current and voltage are both important to avoid damage to the part.  For example, excess current may damage a metal trace due to resistive heating, but excess voltage may damage a transistor by causing avalanche breakdown in the Base Emitter junction. 

    It may be possible that the steps you take to limit device current will also protect from excessive voltage.  For example, series input resistors will both limit current flow as well as reduce the voltage at the amplifier input pins. 

    Regards,
