The MSI integrated interface IC is a multi-channel Sensor interface IC. It generates dynamically to a maximum of 3 Sensor signals by means of current- and voltage- controlled resistance bridges (among other things switch- selectable input sensitivity) and provides subse-quent evaluation systems with A/D- converted signals via digital interface.
Furthermore, the IC enables the equalization of temperature due to an on Chip integrated temperature measurement or loadable reference charts. As well it supplies connected Sensors also with power supply specifications. The IC in particular distinguishes itself besides the on Chip integrated functionality by a high signal solution in the case of simultaneous stability as well as a low power consumption.
The IC is suitable for evaluation of differential Sensor signals, as those that are supplied by pressure sensors, Hall Sensors and Sensors, that work according to the principle of a resistance bridge (e.g. extension bridges, Piezo or Magneto-resistive Sensors).
