Hinweise

  • AD620 chip has a 8 legs. And each of leg is defined as a number 1-8.
  • Capacitor has a 2 legs like led. (+) goes to pin 4 of chip and (-) goes to pin 7 in this case.


How to build Martin howse circuit on brettboard

1. Put the AD620 amplifier on middle of breadboard.

2. Place the 1 k Ω resistor between pin 1 and pin 8.

3. Connect capacitor is connected between pin 4 and pin 7.

4. Place the two 10 k Ω resistors. Both start from pin 5 (reference) with one ending at pin 7 (power, 5 V) and the other at pin 4 (earth, GND)

5. Pin 6 of the AD620 is connected to analog A0.

6. Connect the 3 cables on pin 2,3 and 5. (2,3 is for measuring value between A-B and 5 is for reference.
