ELECTRICAL CONNECTION
Caution! The sensor is not reverse polarity protected.
Incorrect applications of excitation
voltage or ground to the wrong pin can
cause electrical failure.
Application of supply voltage above the
maximum can cause electrical failure.
Note:
A capacitor of 220 nF is required
between +Vs and GND.
Pin 2 is an internal device connection and
should be connected to ground with a
15 nF capacitor.
It is important to place the capacitors as
close to the pins as possible!
Pins 4, 6 and 8 are internal device
connections and should not be
connected for any reason!
