ABSTRACT:
A lead salt detector array where the output voltage of each detector is switched between a signal ground or an amplifier input virtual ground. A switching circuit communicates with each detector. All detectors in the array are switched to a signal ground except for the detector(s) from which it is desired to read a signal. This detector is switched to the amplifier input virtual ground.
