The OPA593 operates from power supplies up to ±42.5 V, or a total of 85 V, with excellent performance. Most behavior remains unchanged throughout the full operating voltage range. A power-supply bypass capacitor of at least 0.1 µF is required for proper operation. Make sure that the capacitor voltage is rated for high voltage across the full operating temperature range. Parameters that vary significantly with operating voltage are shown in Section 6.6.

Some applications do not require an equal positive and negative output voltage swing. Power-supply voltages do not have to be equal. The OPA593 operates with as little as 8 V between the supplies, and with up to 85 V between the supplies.
