3 Op Amp ESD Protection Without Input Diodes to V+

There are several op amps with an alternative input ESD protection structure that does not have a protection diode from both IN+ and IN– pins to V+. This protection behaves differently than the standard protection. Parts with this structure include: OPA310 | OPA2310 | OPA4310, OPA348 | OPA2348 | OPA4348, TLV341 | TLV341A, TLV342 | TLV342A.
