Abstract
A digitally switched analog signal conditioner comprising a plurality of pairs of input terminals, a junction, and an output terminal; a plurality of capacitors, first ends of the capacitors being connected to the junction; a plurality of switches being arranged in pairs, first ends of each pair being connected to the other ends of different ones of the capacitors, the other ends of each pair being connected to respective ones of a pair of input terminals, the switches of each pair being adapted to be operated alternatively; an amplifier having an input and an output, the input being operatively coupled to the junction; and a sample and hold circuit operatively coupled to the output of the amplifier for periodically sampling and holding the output, the output of the sampling and holding circuit being connected to one of the input terminals of one of the pairs of input terminals, the other of the terminals of the one pair of input terminals being connected to a point of reference potential.
