hello guys,
I want to know how can I find correct feedback resistor value in an transimpedance amplifier.
I know for example a photodiode as input:
Vout=Id x R
which parameter in datasheet used for calculating feedback resistor value?
Thanks
R = Vout/Id
The output voltage desired divided by the diode current that should produce it. If you want 1V per microamp,
use 1 megaohm.
