Part Number: LOG200EVM Other Parts Discussed in Thread: LOG200 , Tool/software:
I want to add a chip condensor at C19 and a chip register at R33 on the board, but I couldn't find the information regarding the appropriate package types for these components…
HI Shinya,
1) The RBIAS voltage sets the reverse bias voltage for your photodiode. The optimal RBIAS voltage is dependent on your sensor and application requirement.
As you have mention, a percentage of the I1 current flows through the RBIAS resistor. …
HI Henry,
As alternate solutions, you could consider using a programmable gain transimpedance amplifier or a Logarithmic amplifier solution.
Since the application requires to measure a wide range of current, from 10nA to 1mA., and if the application requires…
