I think the term slew rate is something I have only heard of in recent years. Maybe I haven’t been exposed to such a deep understanding of it before. So I haven’t heard of it.

It is defined as the rate of change of output voltage caused by a large input signal step change. The commonly used unit is V/us. The amplifier is affected by the slew rate parameter. The output signal V changes at the fastest rate due to the large signal response.

until the output signal reaches the same amplitude as the input signal.

Simulation of slew rate:

But I don't understand how the example you give has anything to do with slew rate:

See 2.10.4, it is only related to the full power bandwidth.

If you don't know the relationship between slew rate and full-power bandwidth, it means you don't really understand slew rate.

The voltage conversion rate is the slew rate

I feel that full power bandwidth is difficult to understand
