ELECTRICAL CONNECTION
Note:
Capacitor 220 nF required between +Vs
and GND and 15 nF between Vout and GND.
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!

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.
MEDIA COMPATIBILITY
