Abstract: A pressure sensor device includes a semiconductor die of the pressure sensor device and a bond wire of the pressure sensor device. A maximal vertical distance between a part of the bond wire and the semiconductor die is larger than a minimal vertical distance between the semiconductor die and a surface of a gel covering the semiconductor die.

Abstract: Examples provide for an apparatus, method, and computer program for comparing the output of sensor cells in an arrangement of sensor cells in an area A, including a set of at least two measurement units. A measurement unit includes at least two sensor cells, wherein at least one sensor cell of at least one measurement unit includes a sensitive sensor cell, which is sensitive with respect to a measured quantity. The sensor cells are intermixed with each other. The apparatus further includes means for selecting output signals of sensor cells of the arrangement and means for determining a measured quantity or determining an intact sensor cell by comparing output signals of different measurement units.
