What is the purpose and the definition of the input capacitance parameter in the datasheet.
I have tried to research about this topic but was only able to find the input capacitance parameter with respect to operational amplifiers only. Even after those research, I was not able to understand the concept of input capacitance with respect to this buffer IC.
Can someone help me with my following queries :
- What is the definition of input capacitance of a pin in an IC?
- How is it measured in the first place and is it applicable to all pins in the IC? I am sure, different pins of the IC must have different circuits connected inside. So, the input capacitance of those pins might be different.
Is the input capacitance parameter relevant only to supply/signal pins?
Why should we care about this parameter of the IC while we design our circuit and how is it relevant?
