7.3.1 Operating Voltage

The OPAx388 family of operational amplifiers can be used with single or dual supplies from an operating range of VS = 2.5 V (±1.25 V) up to 5.5 V (±2.75 V). Supply voltages greater than 7 V can permanently damage the device (see the Absolute Maximum Ratings table). Key parameters that vary over the supply voltage or temperature range are shown in the Typical Characteristics section.
