Input ESD Protection

The OPAx310 family incorporates internal ESD protection circuits on all pins. For inputs, this protection primarily consists of fail safe ESD input structures which feature no current-steering diodes connected between the input and positive power-supply pin as shown in the Figure 7-5. This feature is very useful during power sequencing scenarios where input signal can be present before the positive power supply rail. A fail safe input ESD structure prevents any short between inputs and positive power supply.
