●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.

Note:Absolute maximum rating item indicates the condition which must not be exceeded.
Application if voltage in excess of absolute maximum rating or use out of absolute maximum rated temperature environment may cause
deterioration of characteristics.
(*13) The voltage difference between inverting input and non-inverting input is the differential input voltage.
Then input terminal voltage is set to more than VEE.
