I want to use this part to detect low fluorescence over the human skin surface. Has anyone worked with the modulator/demodulator? Will I meet any problem?
For example simple circuit from the application note of AD630 (please find the jpeg)? I want to replace the bridge and instr. apm. with a light-to-voltage transducer with a gain stage. Do I need any phase shifter to adapt the phase of the gain stage to the reference generator signal?
