Hi,

I'm using the op-amp for voltage scaling, the output of the op-amp voltage is using as a reference voltage to the ADC and DAC components. But, the op-amp slew rate is 1V/µs.

So, my question is, do we need to consider the slew rate when you chose the op-amp just for voltage scaling, the input voltage of the op-amp does not change and it is constant voltage.

 

If the op amp input and output are constant DC, then the opamp slew-rate doesn't matter, since that only affects how fast the op amp can change its voltage.
