1.3 Electrostatic Discharge Caution

Some of the OPA598EVM components can be susceptible to electrostatic discharge (ESD) damage. Customers are advised to observe proper ESD handling precautions when unpacking and handling the EVM outside the supplied ESD safe bag and shipment container.

CAUTION: A grounded wrist strap should be worn by the EVM handler at an ESD safe workstation. However, an ESD wrist strap may only be used when circuit voltages are less than 100 V. Do not wear an ESD wrist strap if the potential difference is ≥ 100 V. For circuit voltages ≥100 V, apply an ionizer for ESD control.
