9. Application Circuit and External Components

Application features:



5V module is powered by the application’s electronic control unit (ECU).



Sensor module with 3-pin connector provides pressure measurement data via ratiometric analog output.



The temperature signal for pressure signal correction can be derived either from the on-chip PTAT or from an external diode, PTC or

bridge TC (connected to TS1 or TS2).



End-of-line calibration uses one-wire communication via the AOUT pin.
