Hello everyone,
Now I need to build a precise constant current source to supply a NTC.
In the attachment is my circuits.
Now the problem is , it is able to provide a constant current source, but during I change the value of NTC, the constant current source has a 1uA tolerance. Any idea to get rid of this , and to be more precise?
Thanks!!
