(1) Linear range limited by the maximum output swing to power supply (3V to 5.5V) and ground, not by thermal limitations.
(2) Current levels must remain below both allowable continuous DC/RMS and transient peak current safe operating areas to not exceed device thermal limits. See the Safe Operating Area section.
(3) For more information on the device name and device options, see the Device Nomenclature section.
