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 [math]0.1 \mu[/math] F capacitor between [math]V_{cc}[/math] and ground.

voltage follower/buffer amplifier

  1. Why is this a buffer amplifier?
  2. What is the input impedance ([math]R_{in}[/math])?
