Hello everyone,

I am currently working in a photodiode circuit which creates AC voltage -280mV to +80mV. I need to amplify the circuit using transimpedance amplifier. The output voltage range must be ±10V. How to select a suitable OPamp for this purpose? What factors must be considered? How is the feedback resistance and capacitance value for the circuit calculated?

A transimpedance amplifier takes an input current and creates an output voltage. So you would need to know the minimum and maximum output current of the photo diode, - voltage is meaningless.
