SBOSA11A March 2020 – March 2021 OPA2206
The OPA2206 has two functional modes. The device enters 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 6.
If the input voltage exceeds the device specifications, the device will enter an overvoltage protection mode. In this mode the input overvoltage protection sub-circuit will limit the voltage and current seen by the amplifier core by adding additional impedance between the input pins and the amplifier core. Additional current that is generated from the voltage drop across this input impedance is routed through the ESD structure of the OPA2206, as shown in Figure 8-1.
