    Converting 0-5V to 4-20mA using a Howland Current Pump for Scientists

    I am using a LM741 with an input of 5V and I need a 0-20mA output with a 250ohm load I know that the saturation voltage of the op-amp is +/- 13V. I have calculated my design using a compliance voltage of 5V. How do I post my schematic?

    Converting 0-5V to 4-20mA using a Howland Current Pump for Scientists

    The Howland Current Pump doesn't seem to be working properly. Basically, I need to convert a 0-5V signal to 0-20mA and a 1-5V signal to 4-20mA. If anyone could please help me a.s.a.p!

    Converting 0-5V to 4-20mA using a Howland Current Pump for Scientists

    I have a 0-5V signal which I need to convert 4-20mA by using a Howland Current pump. I know that there are more steps to the whole process but I have misplaced all my notes that I originally had. Could someone please help?
