ABSTRACT:
A sensor array driving circuit includes a plurality of sensing elements arranged in the form of an array, which are commonly connected in a predetermined manner so as to reduce the number of leads or external wiring. The circuit includes a first plurality of transfer switches and a second plurality of transfer switches which are connected to the opposite sides of the sensor array. The circuit includes a single operational amplifier connected between the second plurality of transfer switches and the circuit output terminal. With such a structure, the sensing elements may be easily activated selectively and sequentially to carry out line scanning.
