So, my summer PID job has buffers. I know why buffers are used, but like everything theory and practice are two different things.
Like... I thought buffer would provide a stable current regardless of what happens on the input side (I now this is horrible oversimplification, but that is my basic understanding to the extend of one hour lecture that covered buffers). In the circuit that I am working on, buffers can apparently provide anywhere between 0 to 250 mA of current each. I do not understand this at all. I have read the spec sheets for BUF 634, and it has not made it any clearer.
If someone could make any suggestions... the circuit attached is not exactly the same that I am working on, but is its predecessor and operates on the same principles.
p.s. it will supply current to a laser, or so I am told.
