在电路中,Slew Rate(斜率)是一项重要参数,用于描述电压变化的速度,通常用在运算放大器(Op-Amp)或者其它一些模拟电路中。它定义了输出电压每微秒(µs)变化的最大值,通常表示为 V/µs 或 mV/µs。 例如,如果一个运算放大器的 Slew Rate 是 5 V/µs,这意味着它的输出电压每微秒最多能变化 5 伏特。

Slew Rate 对于确定放大器能够适用的信号频率和类型至关重要。如果一个放大器的 Slew Rate 太低,它可能无法正确地放大频率较高的信号,或在需要快速响应的应用中表现不佳。 Slew Rate 通常在放大器的数据手册中给出,可以通过测量放大器输出从10%到90%(或从90%降至10%)的电压变化所需的时间来实验确定。理论上,...
it amplifies to this voltage to produce an amplified voltage at the output. But sometimes op amps simply function as voltage followers and act as buffers, where there is no gain. Regardless of the reason for which the op amp is used, the slew rate is ...
The slew rate measurement circuit is shown below. The slew rate of an op-amp can be simply measured by providing a step signal toward the input of the operational amplifier. Here, the step signal is a standard signal where this signal exists just for the positive time, and for the negativ...
Slew rate is usually specified in V/μs, perhaps because early general purpose op amps had slew rates in the range of 1V/μs. Very high speed amplifiers are in the 1000V/μs range, but you would rarely see it written as 1kV/μs or 1V/ns. Likewise, a nanopower op amp might be...
Learn how to get faster composite op-amp dynamics by raising the slew rate. This article is the fourth in a series on amplifiers. In the first article, we discussed how to boost an op-amp’s output current drive capability. In the second, we discussed how to learn more about the method...

Slew Rate of Op Amp Circuits:The slew rate (SR) is defined as the maximum rate of change of the output of an op amp circuit. The SR in general describes the degradation effect on the high frequency response of the active amplifier (one with an op amp) near or at the rated maximum ...
