Reference voltage, VREF
The IQAN module is internally equipped with a voltage regulator to generate the
reference voltage VREF. The standard reference voltage will feed different kinds of
sensors and potentiometers.
On the IQAN-MD4 there is no -VREF pin, instead the -BAT is used as -VREF. To get
the best result, connect as close to the connector as possible to minimise voltage
fluctuations. In connection examples that follow, -VREF will refer to the -BAT pin.
VREF positions.
NOTICE
Maximum load for the VREF is different according to 12/24 Vdc power supply, see
"Appendix A".
