    the op. amp. doesn't work as it should

    I connected the photodiode (current source) as shown: If i measure the voltage across + and - input of op. amp. i don't get 0V, but the voltage rises proportional to current from current source. How is that possible? Rolling Eyes The op. amp. is TLC2272 and Vcc is 5V. I get 0.35V across at...
