    · An amplifier with a high input impedance (ZIN) will have·little effect (load) upon the circuit to which it is connected.· Impedance (Z)·is analogous to resistance (R); ZT = (Z1*Z2) / (Z1+Z2)

    · An ideal amplifier (esp. an op-amp) would have infinite ZIN.

    · What's a 74__03?· Did you mean 74__08?
