  11. TINA Exercise-BW

  12. NI myDAQ Exercise-BW • Populate U2 with OPA333 • Set J2 to pins 2-3

  13. NI myDAQ Exercise-BW • Launch Bode • Start Frequency=100Hz • Stop Frequency=20kHz • Steps=10 • Peak Amplitude=0.05 • Run

  15. Compare Results

  16. Further Reading

  17. Backup/Extra

  18. Revisions • 0.2 – channgedbw lab. • Changed sim file to include non-inv • corrected inverting gain to 30.83db • Corrected -3db sim. Show that sim model doesn’t match calc • corrected simvs measured. • Added table to compare calc, sim, meas
