Information
Non-Inverting Op Amp
An operational amplifier (often op-amp) is a DC-coupled high-gain electronic voltage amplifier with a differential input and, usually, a single-ended out put.
Below is a link to the Texas Instruments 741 Operational Amplifier Spec Sheet that goes in depth on configuration and functions of the circuit:
Set-Up
Lab
The images above display the given lab set-up
Configuration 1:
The graph above shows a Rf of 10k and R1 of 10k. When calculated the theoretical gain of the amplifier came out as 2V, however when applied and measured with the oscilloscope in lab the gain was 2.18V
Configuration 2:
The graphs below show a 14kHz ramp wave with an amplitude of 0.55Vpp ran through the circuit
The graph above shows a Rf of 27k and R1 of 10k. When calculated the theoretical gain of the amplifier came out as 3.7V, however when applied and measured with the oscilloscope in lab the gain was 3.82V
Configuration 3:
The graph above shows a Rf of 27k and R1 of 5.6k. When calculated the theoretical gain of the amplifier came out as 6V, however when applied and measured with the oscilloscope in lab the gain was 6.12V
