Cooler Than Absolute Zero!
An operational amplifier (op-amp) is an integrated circuit (IC) chip that contains a high-gain differential amplilier. The inputs have very high input impedance and draw essentially no current.
Schematic of an op-amp in an inverting amplifier circuit oops!
In this circuit the output voltage is governed by the following relationship: Vout = -Vin ( Rfeedback / Rin ) Related Topics
