Hi,
We are looking for Load Independent constant current source, current value will be 5mA. Load resistance will vary from 650 Ohm to 850 Ohm. Input power is 5V.
Also, it should have lower temperature coefficient, because this is going to be implemented in Sensor application.
Do we have IC for this application?
Op amp based constant current source may have drift in output with temperature.
I experimented the same with LM334, but output is varying with change in load.
Thank you,
Regards,
Rajesh Matere.
