I am trying to understand the LM4250 op-amp. Datasheet:
Pin-outs for DIP:
It appears that pin 8 (quiescent current set) can be used to change the quiescent current, according to this table:
My question is: why would you want to do this (change the current)? My understanding of quiescent current is that this is the minimum amount of current consumed by the device (not under load). Why would you want this to be any higher than the minimum the device is capable of?
Also, what is this symbol?
