8.3.3 ESD Protection

Figure 8-1 shows that all device pins are protected with internal ESD protection diodes to the power supplies. These diodes provide moderate protection to input overdrive voltages greater than the supplies. The protection diodes typically support 10-mA continuous input and output currents. Use series current limiting resistors if input voltages exceeding the supply voltages occur at the amplifier inputs, which makes sure that the current through the ESD diodes remains within the rated value. OPA2863-Q1 is a bipolar amplifier; therefore, the two inputs are protected with antiparallel, back-to-back diodes between the inputs that limits the maximum input differential voltage to approximately 1 V. Make sure to use gain-setting and feedback resistors large enough to limit the current through these diodes in fast slewing conditions.
