Not sure exactly how to word this but I'll give it a shot. In my project a detector will output anything from 16uV to 750mV. To succusfully trigger a Time-to-Digital converter the voltage around the minimum of 16uV will not suffice to it needs to be amplified. I have an amplifier and comparator circuit that will achieve this, however I do not need/want it to amplify when the voltage is above 100mV. Is there anyway to set it so anything lower than 100mV will go to the amplifier and anything 100mV and above will go straight to the detector. It also needs to be in an analog way.
If input<100mV go to amplifier then to detector
If input>100mV go to detector
If clarification is needed I'll be happy to try
