Definitions

  • the invention is based on a device according to the type specified in the preamble of claim 1.
  • FIG. 1 shows an embodiment of this known voltage divider.
  • FIG. 2 shows the associated equivalent circuit diagram.
  • the voltage divider consists of a first resistance layer 1 produced in thin or thick-film technology with an area 11 serving for the supply of current and connected to a conductor 3 and with an area serving for dissipation of current being connected with a conductor 4.
  • the conductors and resistance layers are made from those used in hybrid technology Conductor and resistor pastes made.
  • the tap consists of a second resistance layer 2, which overlaps the first resistance layer 1 in a contact zone 9 and connects it to a third conductor track 5 provided as a removal electrode.
  • a laser or sandblast cut 10 is made in the second resistance layer, which cuts the potential lines formed during operation of the voltage divider.
  • the cut 10 is made until the potential at the take-off electrode 5 reaches the desired value.
  • the ohmic voltage divider resistor through which current flows is formed from a single coherent resistance region 1 with a resistor R1, which is only divided into two partial resistors R1 'and R1''by the tap, as shown in FIG. 2. Since the partial resistors Rl 'and Rl'', which are connected in one piece, consist of the same material with the same temperature coefficient, in contrast to a voltage divider with two spatially separated resistance layers made of different materials, temperature dependence of the tapped voltage value can be largely excluded. In addition, by laying the cut necessary for the adjustment in the second resistance layer 2, the potential distribution within the current-flowing voltage divider resistor R1 remains essentially constant.
  • the known voltage divider arrangement does not meet every requirement profile. For example, in cases where a very small
  • the divider voltage is to be tapped at the resistor R1, one of the two partial resistors formed will become very small, for example the partial resistor R1 '' if the divider voltage is tapped at the second conductor track 4 and the third conductor track 5.
  • the resistance ratio Rl '/ Rl'' is significantly greater than five in these cases. This leads to problems because the area requirement of the voltage divider arrangement within the integrated layer circuit should be as small as possible (as a rule, the length of the resistance layer R1 is about 5 mm, the width is about 2 mm), but at the same time
  • the partial resistances Rl 'and Rl''must be tapped to an accuracy of at least one percent.
  • the voltage divider arrangement according to the invention with the characterizing features of claim 1 has the advantage that even very small divider voltages can be tapped at the take-off electrode and at the same time the area requirement for the voltage divider arrangement is increased to a significantly smaller extent than in the prior art must become. This is achieved by connecting the second resistance layer to the first resistance layer not directly, but via conductor tracks, a first divider voltage tapped at the first resistance layer being applied to the second resistance layer. Only a part of this first divider voltage is now advantageously tapped at the take-off electrode connected to the second resistance layer, so that overall very small divider voltages can be generated.
  • the area required for the arrangement is increased only by the space for the laying of the additional conductor tracks and by the geometric expansion of the second resistance layer.
  • this additional area requirement is far less than in the prior art, so that the area requirement of the arrangement does not increase disproportionately even with very small divider voltages desired.
  • the alignment of the arrangement carried out by an incision in the second resistance layer can be carried out with the required accuracy, since the geometrical dimensions of the partial resistors formed in the first and in the second resistance layer provide the minimum necessary for an exact alignment. Do not undercut minimum size. The partial resistors can therefore still be tapped to within one percent even with small divider voltages.
  • transverse resistance Rl '+ Rl' 'of the first resistance layer remains constant during the adjustment, since the adjustment is carried out by an incision in the second resistance layer, which is spatially separated from the first resistance layer.
  • the second and fifth conductor tracks are also advantageous to have the second and fifth conductor tracks as one piece with the second region of the first Resistance layer connected conductor track to provide, since this facilitates the layout and execution of the voltage divider arrangement in hybrid technology.
  • only one conductor track is provided as a removal electrode on the first resistance layer.

Abstract

L'invention concerne un ensemble diviseur de tension ajustable, fabriqué selon la technique hybride, comportant une première couche de résistance ohmique traversée par le courant, disposée entre deux tracés conducteurs, et une deuxième couche de résistance raccordée électriquement à la première couche de résistance. Un troisième tracé conducteur, conçu en tant qu'électrode de prélèvement, est raccordé à la deuxième couche de résistance. Afin d'ajuster le diviseur de tension, une entaille est réalisée dans la deuxième couche de résistance de sorte qu'une valeur de tension souhaitée puisse être prélevée au niveau de l'électrode de prélèvement. Afin de pouvoir prélever de très faibles tensions de diviseur avec la précision requise, sans augmenter excessivement l'encombrement de l'ensemble diviseur de tension, il est prévu de raccorder la deuxième couche de résistance à la première couche de résistance par l'intermédiaire de tracés conducteurs de façon à appliquer au niveau de la deuxième couche de résistance une première tension de diviseur, prélevée au niveau de la première couche de résistance, et de sorte qu'une partie de la première tension de diviseur puisse être prélevée au niveau de l'électrode de prélèvement raccordée à la deuxième couche de résistance.
