Operating Voltage
The OPAx364 series of operational amplifier parameters are fully specified from 1.8 V to 5.5 V. Single 0.1-µF
bypass capacitors should be placed across supply pins and as close to the part as possible. Supply voltages
higher than 5.5 V (absolute maximum) may cause permanent damage to the amplifier. Many specifications apply
from –40°C to 125°C. Parameters that vary significantly with operating voltages or temperature are shown in the
Typical Characteristics.
