    what does || mean on a datasheet?

    Hi,

    I am reading an application note on op-amps and it uses the following notation:

    For R1 = R3 and R2 = R4:
    Vout = (R2/R1)(Vin2 – Vin1)
    R1 || R2 = R3 || R4
    for minimum error due to input bias current


    What does the || mean in this context? I know it means OR in many programming languages, is that what it means here too?

    another example from the same document is:

    Vout = – R2(Vin1/R1 + Vin2/R2 + Vin3/R3)
    = R1A || R1B || R1C || R2
    for minimum error due to input bias current


    I have tried searching on Google but I cannot find anything definitive.

    Thanks

    Tim

    Okay, that makes sense.

    Thanks

    davenn, FYI, The link is:

    A Single-Supply Op-Amp Circuit Collection

    It is a useful little document if you want to get your head around using Op-Amps.
