7.4 Device Functional Modes

The OPAx206 have two functional modes. The devices enter normal operation with any supply between 4.5 V (±2.25 V) and 36 V (±18 V), and an input voltage that meets the input common-mode voltage range shown in Section 5.

If the input voltage exceeds device specifications, the devices enter an overvoltage protection mode. In this mode, the input overvoltage protection subcircuit limits the voltage and current seen by the amplifier core by adding additional impedance between the input pins and the amplifier core. Figure 7-1 shows how additional current that is generated from the voltage drop across this input impedance is routed through the ESD structure of the OPAx206.
