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.).
