We are looking for Load Independent constant current source, Load 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.
I do have size constraint on board, so I am looking for less component solution. While working on TI website, I found following design.
Will this work as Load independent ( 650R to 850R) 5mA constant current source?
