9 Power Supply Recommendations

The OPA455 operates from power supplies up to ±75 V, or a total of 150 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 rating is suitable for the high voltage across the full operating temperature range. Parameters that vary significantly with operating voltage are shown in the Typical Characteristics section.

Some applications do not require an equal positive and negative output voltage swing. Power-supply voltages do not have to be equal. The OPA455 operates with as little as 12 V between the supplies, and with up to 155 V between the supplies.
