Reference voltage, VREF

     

Instruction book, IQAN-MD4

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.

N

OTICE

Maximum load for the 

VREF

 is different according to 12/24 Vdc power supply, see 

"Appendix A".
