Construct a Schmitt Trigger using the 741 Op Amp

Draw the Schmitt Trigger circuit you constructed. Identify the values of all components

Schmitt trigger 01.png

To construct the circuit above I am going to use the following components and voltages:

  1. [math]R_1 = (1.01\pm0.01)\ k\Omega[/math]
  2. [math]R_2 = (1.01\pm0.01)\ k\Omega[/math]
  3. [math]R_3 = (5.10\pm0.01)\ k\Omega[/math]
  4. [math]\mbox{OP}\ \mbox{AMP}\ 741[/math]
  5. [math]V_{ref} = (+11.90\pm0.01)\ V[/math]
  6. [math]V_{cc} = (+11.90\pm0.01)\ V[/math]
  7. [math]V_{ee} = (-12.11\pm0.01)\ V[/math]

Graph [math]V_{out}[/math] as a function of [math]V_{in}[/math]. Is there a hysteresis loop?

Identify the input voltage threshold levels at which a [math] V_{in}[/math] will produce [math]V_{out} \approx V_{cc}[/math]

Compare the threshold values to what is expected.
