As lab supervisor testing ICs is not the most joyful part of your jab, building a testing platform will enhance the efficiency, reliability and save your time So here I created this PCB for the most used ICs in my lab as a Biomedical Engineer

This project is intended to be used to test the functionality of the following ICs:

  • TL071
  • TL072
  • LM741
  • 555 Timer The testing process will be done using a Function generator and Oscilloscope

the Op-Amps have a gain of 2 and configured as inverting amplifiers with powering voltage up to +-15V DC

the 555 timer is configured as Astable multivibrator with the following parameters: Periode => T=0.01sec
Frequency => f=100.0693Hz Duty cycle => D=52.8%
