#68982 - D/A PWM 4 - 20 mA |
Hello,
I am trying to design an analog circuit to create a 4 - 20 mA current loop using the PWM on a Cygnal 8051 micro. How do I go about doing that? Is there an app note out there that describes info and components needed. Somebody had mentined about using a resistor and capacitor but the textbooks I have do not mention this method. |
