Abstract
An apparatus for issuance of at least one electrical output signal (Iout), wherein the desired electrical current level of the output signal (Iout) is predeterminable, including: at least one measuring resistor, at which the electrical current level of the output signal (Iout) is measurable; at least one adjuster, via which the electrical current level of the output signal (Iout) is settable; and at least one controller, which compares the electrical current level of the output signal (Iout) measured at the measuring resistor with the electrical current level desired for the output signal (Iout), and which controls the electrical current level of the output signal (Iout) via the adjuster; wherein the controller and the measuring resistor are connected with an electric base-potential (VGND); and wherein the base-potential (VGND) is a reference potential for the controller.
