Dear team,
My customer would like to know whether XTR305 is proper device to meet their requirement like below.
- Input signal : -10V to +10
- output signal : 4 to 20mA
Current solution is like below but they want to convert from discrete to XTR series. Please let me know your opinion whether XTR305 is proper solution or not.
If XTR series is available for this application, please share application note or reference design.
Thank you.
Hi Dino,
Yes, the XTR305 can work on this application.
Attached is a XTR305 simulation example, the device is configured in current output mode, powered with bipolar ±15V supplies.
The -10V to +10V input signal is fed through a voltage divider 15kΩ - 10kΩ referred to a +10V reference to produce a 2V-10V voltage at the VIN input pin of the XTR305. The RSET resistor is set to 5kΩ. The circuit produces a 4-20mA output, for a -10V to +10V input signal.
Please see TINA-TI circuit and simulation result below.

Thank you and Kind Regards,
