Design engineers aiming to protect the input and output of op amps have several options. They can use an electrostatic discharge (ESD) diode or input current-limiting resistor alongside a transient voltage suppressor (TVS) diode. However, both design approaches have limitations. Here is why an op amp with integrated JFET input protection has better design merits.
