I am trying to measure the voltage coming out from my OpAmp after connecting it to my Photodiode. As a Photodiode I am using the BPW34S from Vishay and the Op Amp is the AD822ANZ from Analog Devices. According to the Analog Devices Photodiode Circuit Wizard the following image should be my connection:
The Cathode of my Photodiode is connected towards the Op Amp, while the Anode is connected to the Ground. I am using a 9V Battery to power my Op Amp as a single supply. The '-IN1' is connected as shown in the above image, '+IN1' is connected to the ground, as is 'V-' and 'V+' is connected to the positive side of the 9V Battery. As ground I am using the negative side of the battery. (I have also tried using the 5V and GND output of a RaspberryPi 4 but I thought that maybe I was not getting enough Voltage).
I have measure the voltage between the Vout and the Ground of the battery with a Voltmeter, but I always get a value of 0V as output from my OpAmp and there is no change when I put more light on my Photodiode.
My Photodiode is working when I connect it simply with a resistor and measure the Voltage passing through the resistor. But I need it to work with an OpAmp as I want to connect it to an ADC afterwards.
I am doing something wrong with the wiring or is there a problem with my Op Amp?
