●Description
General-purpose BA10358/BA10324A family and high-reliability BA2904 /BA2902 family integrate two or four independent
Op-Amps and phase compensation capacitors on a single chip and have some features of high-gain, low power
consumption, and operating voltage range of 3[V] to 32[V] (single power supply ). BA3404 family is realized high speed
operation and reduces the crossover distortions that compare with BA10358 family.

(*12) 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.
