slew rate定义:闭环放大器输出电压变化的最快速率。用V/us表示。 此值显示运放正常工作时,输出端所能提供的最大变化速率,当输出信号欲实现比这个速率还快的变化时,运放就不能提供了,导致输出波形变形——原本是正弦波就变成了三角波。 对一个正弦波来说,其最大变化速率发生在过零点处,且与输出信号幅度、频率有关...
Slew rate is the maximum rate of voltage change that can be generated by the op-amp’s output circuitry. It is measured as voltage relative to time, and the typical unit used in datasheets is volts per microsecond (V/µs). Let’s say you have an op-amp and apply an input signal...
The slew rate of an operational amplifier indicates how fast its output voltage can change. The output of an Op-Amp can only change by a certain amount in a given time. This limit is called the slew rate of the Op-Amp. Op-Amp slew rate can limit the performance of a circuit if the...
