求翻译：1960年代晚期，仙童半导体推出了第一个被广泛使用的集成电路运算放大器，型号为μA709，设计者则是鲍伯•韦勒。但是709很快地被随后而来的新产品μA741取代，741有着更好的性能，更为稳定，也更容易使用。是什么意思？

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
