A valve with a structure limiting of the turning angle of the valve knob includes a valve and knob installed on the valve. Parallelepiped-shaped transducer elements are used as transducer elements and a plurality of such transducer elements are arranged in an array. By implementing the certain input code range into the smaller switch array area, further improved linearity in that input code range is achieved at the expense of worse linearity in the other input code ranges, but without increasing power consumption andor chip-area of the integrated circuit die. The alternating phase shift pattern has a plurality of pairs of first non-transparent regions.
