OP Amp applications

Construct the OP amp circuits and measure their range of operation with respect to the input frequency, voltage, and when appropriate their output load.

- It will be a good idea to connect a F capacitor between and ground.

# voltage follower/buffer amplifier

- Why is this a buffer amplifier?
- What is the input impedance ( )?

# Difference Amplifier

- How can you make the input impedance the same for and ?
- Measure for several values of and . Plot and compare the slope to R1 and R2.

# Summing Amp

- Measure for several values of and .
- Use the above measurement to show how and are summed.

# I-to-V converter

- Plot the measured valued of I_{in} and V_{out} for the circuit above.

# V-to-I converter

- Plot the measured valued of V_{in}and I_{out} for the circuit above.
