(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.
