How do I design a TIA with different transimpedance gain paths with the
ADA4350?

 

To design a TIA, it is essential to know how the total capacitance (photodiode
capacitance + amplifier input capacitance + PCB board capacitance), feedback
resistor and feedback capacitance interact to determine the stability, signal
bandwidth and noise. You can read more about the Transimpedance Amplifier
Design Theory in the ADA4350 datasheet. Then you can apply the same principle
to design each gain path. A TIA Calculator tool is also developed to automate
the design process. Please email zoltan.frasch@analog.com for a cop
