Date: April 10, 2008 To: Jamil Suleman From Ted Thompson Subject: Op-Amps Lab 9 An operational amplifier or op-amp is a dc - coupled high-gain electronic voltage amplifier with differential input with a single output. Typically the output of the op-amp is controlled either by negative feedback , which largely determines the magnitude of its output voltage gain, or by positive feedback , which allows for a regenerative gain and oscillation. It has characteristics of high input impedance at the input terminals and low output impedance. Inverting amplifier inverts and amplifies a voltage. A non-inverting amplifier just amplifies the voltage. And, an integrated amplifier is used to integrates the inverted signal over time. In this experiment, an op-amp was used in an open loop, inverting amplifier with open loop gain, inverting amplifier with closed loop gain, and an integrated amplifier circuit. In the open loop circuit the voltmeter reads 14.5v which is half the potential of the two
