Sir

kindly please send me a circuit diagram that converts 0-9V to 4-20mA.thanks.

What is the need of the transistor at the output? Can i do away with the transistor? What is the problem in using a circuit with op-amps alone?

hi.

more useful.done a good job

Article was superb. Self explanatory

I need a circuit for 0-10V input and 4-20mA output.

I have the input of 0 to 10 volt with 0 to 6khz input power supply, from that I have to get an output of 10uA to 10A linearly (Current Source) .

that is if the input voltage 10V means I should get an output as 10A and if I reduce the input voltage linearly,

then the output current also will vary linearly. the minimum value is 10uA.

Nice to see some basic electronics that have basic but useful applications. Thanks.

This has proven to be a useful circuit for driving lamps and even as a battery charger. The two major advantages are that the load is tied to ground and that it uses a single supply. Further advantages are that it can be scaled to large loads by replacing the shunt transistor (e.g. with a TIP117), and that feedback can be integrated easily.

the expression for IL for single rail is slightly wrong. A factor of two is missing. Derive and see where!!!

good circuit ; well explained ....
