Hi all, First post so go easy!
I have looked through countless posts on this before asking but none seem to be straightforward or else i need them to be explained more easily
I need to develop a 4-20mA supply to fed an inverter for a project.
The inverter has a 24v output on it i can use to power the circuit or i can strip down an old mobile charger to give me 5v or i can make a PP3 9v batttery powered unit
I have been given an XTR110kp and some knowhow of circuits and components. What i dont know is how to do it.
The datasheet says 10v or 5v Vin but also a Vcc of upto 40v.
Can i just power up the chip with 5v to Vin2 and use variable resistors accordingto the datasheet values to generate the 4-20 or do i need the 5v to be variable?
If the inputs need to be a variable 0-10v (Vin1) or 0-5v (Vin2) how do i do it? with what i've got to hand.
I can get pots and resistors and other small components readily enough but dont want to have to buy a variable power supply or expensive components.
I do have couple of Fluke multimeters etc so can use them to measure mA and voltages etc
