Below is a transimpedance amplifier (OPA380) that I'm using to convert a pulsing current signal from a photodiode in (SFH7050).
Everything works as expected when I was using 2.5V and -2.5V as supply, eg. output voltage and frequency response.
When I change the supply voltage to 3.3V and GND as supply, everything just changed. In this case, the frequency response slide downwards from 1kHz onwards and the output voltage is not the same as before. The output voltage drop from V to mV.
I can't figured out what's wrong as the datasheet mentioned it could operate in a single supply from 2.7V - 5.5V. I can't post more than 2 links currently, so I'll try to provide more info in the comments.
