The late 1960s, Fairchild Semiconductor introduced the first widely used integrated circuit operational amplifier, model μA709, the designer is Bob ? Weller. But then came the 709 soon to be replaced by new products μA741, 741 has better performance, more stable, easier to use.

In the late 1960s fairy boy semiconductor introduced the first widely-used integrated circuit operational amplifier, model 709, a designer is μA bobber ? Weller. But 709 very quickly and was then in new products should be replaced by 741 to 741 A has a better performance, more stable, and easier to

Today operational amplifier, regardless of were uses the transistor or the vacuum tube, the separation type part or the integrated circuit part, the operational amplifier potency all already gradually approached the ideal operational amplifier the request.The early operational amplifier is uses the

Late 1960, FAIRCHILD semiconductor has introduced the first widely used integrated circuit operational amplifier, model for μ A709, designers were Bob widlar. 709 quickly be replaced by the following new products Mu A741, 741 has a better performance, more stable, easier to use.
