It is recommended to protect the pressure sensor IC against overload and electro-magnetic interferences (as
shown in
The output circuit acts as a low-pass decoupling filter between the sensor IC output and the A/D input of the
microcontroller.
The shown application circuit example considers an increased cable length between the sensor and the
microcontroller. A combined location on a PCB with reduced distance between the sensor and the controller allows
a reduction of the numbers of the passive components (e.g.
