Today I tested the attached circuit which basically works as expected but after maybe one minute, the opamp becomes rather warm if not hot to touch.
Am I asking too much from it? The current, as shown is 11 mA (steady) through the whole range.By reading the datasheet I could not conclude if I am exceeding anything. Honestly, I do not know where to look at for this.
With the scope I can see noise everywhere, of up to 50 mV pk-pk. The whole PCB appears plagued by that noise.
Any comment, appreciated.
Had to use Paint for drawing instead of Corel. Sorry if it looks horrible.
