(Note 12) Current Direction: Since first input stage is composed with PNP transistor, input bias current flows out of IC.
(Note 13) Under high temperatures, please consider the power dissipation when selecting the output current.
When the output terminal is continuously shorted the output current reduces the internal temperature by flushing.
