Feature Description (continued)

7.3.2 Input Protection

The input stage of the OPA207 is internally protected with resistors in series with diode clamps as shown in

Figure 36. The inputs can withstand ±10 V differential inputs without damage and the maximum input current

should be limited to 10 mA or less.. The protection diodes conduct current when the inputs are over-driven such

as when the opamp output is slewing. This may disturb the slewing behavior of unity-gain follower applications,

but will not damage the operational amplifier.

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.
