1.2 High-Voltage Warning and Safe Use

As previously mentioned, the OPA593 op amp can use a power-supply voltage as high as 85 V in a single-supply connection, or ±42.5 V in a dual-supply connection. Both supply conditions represent a potential difference of 85 V. Voltage potential differences of 50 V or greater are potentially lethal to humans and must be treated with a higher level of caution and awareness than when working with low voltages. Consult your company’s established high-voltage best practices and follow them when using this EVM. Do not leave the EVM unattended when high-voltage is present.

Additionally, keep in mind that the OPA593 is a power op amp. The OPA593 and the output load can generate enough heat to become hot to the touch under some operating conditions. Exercise caution when working with the EVM to avoid physical contact with the OPA593 and the load that the device may be driving in case either become hot.
