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. R1=(1.01±0.01) kΩ
  2. R2=(1.01±0.01) kΩ
  3. R3=(5.10±0.01) kΩ
  4. OP AMP 741
  5. Vref=(+11.90±0.01) V
  6. Vcc=(+11.90±0.01) V
  7. Vee=(12.11±0.01) V

Graph Vout as a function of Vin. Is there a hysteresis loop?

Identify the input voltage threshold levels at which a Vin will produce VoutVcc

Compare the threshold values to what is expected.
