7.3.3 ESD Protection

The OPA207 is internally protected against ESD events that can occur during manufacturing, handling, or

printed-circuit-board assembly. The internal ESD protection diodes are not intended to protect the OPA207

during normal operation when the device is operating under power. In cases where the inputs or output can be

driven above the positive power supply or below the negative power supply care must be taken to limit the

current through the internal diodes to 10 mA or less. In harsh electrical environments external protection circuitry

may be required and is dependant upon the application requirements and environmental conditions.

7.3.4 Input Stage Linearization

The OPA207 uses linearization techniques to reduce the total harmonic distortion. Figure 38 illustrates the

linearization concept, and Figure 38 illustrates the total harmonic distortion performance of the OPA207.
