Other Parts Discussed in Thread: OPA27

Dear sir

i am using OPA27 op-amp as i observed it gives more than 1volt  output with 0v at 5mv signal input. 

I also tried this op amp with unity gain but output was 1.28 volt.

How i can solve this issues.

i want to use this op amp with a photo diode for light detection with different sample b/w light and photodiode.

    Hi Sandeep, I dont get it right.. "i am using OPA27 op-amp as i observed it gives more than 1volt output with 0v at 5mv signal input. " does that mean you give 0V input or 5mV input.. Can you clarify or add the schematic of the circuit for more details.

     

    Thanks
