LM318DR单路高速运算放大器

说明：

　这个LM118,LM218,LM318是精密、快速运算放大器设计为应用程序需要宽的带宽和高转换速率。他们有一个十倍增长速度超过通用设备在不牺牲直流性能。

这些运算放大器有内部单位增益频率补偿。这大大简化了他们的应用程序,因为没有外部组件操作是必要的。然而,与大多数内部补偿放大器、外部频率补偿可以添加为最佳性能。对于反相的应用,前馈补偿提高了转换速率超过150 V /μs和几乎两倍的带宽。过度补偿可以用放大器更稳定的时候

The LM118, LM218, and LM318 are precision, fast operational amplifiers designed for applications requiring wide bandwidth and high slew rate. They feature a factor-of-ten increase in speed over general-purpose devices without sacrificing dc performance.

These operational amplifiers have internal unity-gain frequency compensation. This considerably simplifies their application because no external components are necessary for operation. However, unlike most internally compensated amplifiers, external frequency compensation may be added for optimum performance. For inverting applications, feed-forward compensation boosts the slew rate to over 150 V/µs and almost double the bandwidth. Overcompensation can be used with the amplifier for greater stability when maximum bandwidth is not needed. Further, a single capacitor can be added to reduce the settling time for 0.1% error band to under 1 µs.

The high speed and fast settling time of these operational amplifiers make them useful in A/D converters, oscillators, active filters, sample-and-hold circuits, and general-purpose amplifiers.
