Voltage to current conversion

ad694 current transmitter

How do I convert a 0-10V voltage signal to 4mA-20mA current signal ?

U can Use Current op Amp

 

[Davood Amerion]

where you use 4-20mA?
I think (usually) all instrumets accept 0-10V input, instead!

is it ac or dc

You are talking about a current loop. You usualy do this with optocouplers. Take a look at Agilent HCPL-4100 optocoupler. It is made for this job.

I saw some ICs from TI, pls search in TI's website. www.ti.com

Try: XTR110 ..
It's precission voltage to current converter from former Burr-Brown - today it's Texas Instruments ..

AD694 also is a 4-20mA Monolithic Current Transmitter.You can use it!

Dear IanP,
Thank you for our reply. XTR110 can indeed be used in my circuit.

you can use U/I isolated amplifier module directly
