Note that you can put 2 or more mosfets in paralell. Rdson will be smaller, but driver will be more loaded.

Hi Mike, Thanks for the comment!

The potentiometers I’m using are part number P12426CT-ND at Digikey.

This is a beautiful piece of work. Care to email me the digikey part number for those potentiometers? I’m looking for a part just like that myself.

Hi Martin,

I believe you’re confusing the operation of P and N channel FETs. As the paragraph below figure 3.2 states, the P and N channel fets are activated by opposite polarities.

Thus, the interface circuit is correctly set up to provide a high signal to Q4, and a low signal to Q1 to switch them both on, while ensuring that the others are off.
