AD8180. Current limit in the input

Hi,

The same should also apply to this product. With the exception of when it is turned off, it is true that the current shall be limited to 5mA at any time but looking at the absolute maximum ratings voltage at the input pin should be kept at within the supply range, This will be clearly violated during turn off. Violating the abs max rating  may cause permanent damage to the device also, exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Hi Mr Gauzz.

Thansk for your answer but i need further clarification.

AD8180 : +-Vs

AD8129: *Vs-0.3, - Vs+0.3

So the problem is that AD8180 lack of EDS diode protection (the +-0.3V) at the input for AD8180?

So i must add a 3rd component (ESD diode at the input)?

1)ESD protector (bidirectional varistor with very low capacity)

2) a resistor that keep the current lower than 5 mA (the ESD protetor clip the tension to +-10-20V even in the case of ESD 8-15Kv impulse)

3) add ESD diode at the input IN0, IN1 toward +Vs and -Vs

Is it a possible solution?

Best regards
