Re: Suggestions for analog switch to select feedback resistor in TIA



Hello Kevin,

Not sure what you are trying to do but AD has lots of nice logamps. That and a low noise current to voltage converter might do.

Anyway, if you are looking for a very low capacitance switch there is a nice quad array: SD5400. But it ain't cheap, several Dollars. For some reason the Vishay site doesn't seem to find it today but that site seems to have problems at times.

Regards, Joerg
