The OPA548 operates from single (8 V to 60 V) or dual (±4 V to ±30 V) supplies with excellent performance. Most behavior remains unchanged throughout the full operating voltage range. Parameters which vary significantly with operating voltage are shown Typical Characteristics.

Some applications do not require equal positive and negative output voltage swing. Power-supply voltages do not must be equal. The OPA548 can operate with as little as 8 V between the supplies and with up to 60 V between the supplies. For example, the positive supply could be set to 55 V with the negative supply at –5 V, or vice-versa.
