6 Pinning
All power supply pins (1V2, 2V5, 3V3) must be connected.
All ground pins (GND, GND_REF) must be connected.
All pins specified as n.c. (=not connected) must be left open.
Info
Analog inputs (AI) are 2.5V single ended inputs. Voltage dividers are required to
scale down higher input voltages.
Digital inputs (I) resp. (IO) are 3.3V single ended inputs. Voltage dividers are
required to scale done higher input voltages.
