General Description
General purpose BA8391G/BA10393F/BA10339xx
and high reliability BA2903xxxx/BA2901xxx integrate
one, two or four independent high gain voltage
comparator. Some features are the wide operating
voltage that is 2V to 36V (for BA8391G/BA10393F/
BA2903xxxx/BA2901xxx) 3V to 36V (for BA10339xx)
and low supply current. Therefore, this series is
suitable for any application.
Features
Operable with a Single Power Supply

(Note 31) Current Direction: Since first input stage is composed with PNP transistor, input bias current flows out of IC.
(Note 32) 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.
