8.3.2 Operating Voltage

The OPA363 and OPA364 series op amp parameters are fully specified from 1.8 V to 5.5 V. Single 0.1-µF bypass capacitors must 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.
