General Description
General purpose BA10358 / BA10324A and high
reliability BA2904 / BA2902 integrate two or four
independent Op-Amps on a single chip and have some
features of high-gain, low power consumption, and
wide operating voltage range of 3V to 36V (single
power supply ).
BA2904W have low input offset voltage(2mV max.).
Features
Operable with a single power supply
Wide operating supply voltage range
Input and output are operable GND sense
Low supply current
High open loop voltage gain
Wide temperature range
Application
Current sense application
Buffer application amplifier
Active filter
Consumer electronics

(Note 24) 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.
