A linearization circuit with digital element matching for digital-to-analog converters includes an n-bit delta-sigma modulator that receives an input signal and provides a modulated n-bit signal. The pin electronics circuit includes a pin driver having an output adapted for coupling to a device-under-test pin, and a first input. The fluorine reduces the viscosity of the silicon oxide isolation region during formation which results in less lateral, bird’s beak encroachment under adjacent masking stacks and also results in lower internal stress in the isolation region during formation. Units are arranged in the space so the per-unit reader locations at least partially overlap to define a reader location. The support frame includes a simple structural design, in which the longitudinal members are detachably joined to the face plates such that the ends of the longitudinal members are pressed against a bearing surface of the face plates in the direction of their lengthwise axis, transversely to the longitudinal member. The wipers are fastened on wiper carriers, which are in the form of gearwheels, frictional wheels or crank disks, are pivot-mounted on the printed circuit board and are gear-connected to the reduction gear andor the manipulatable member.
