Application information (continued)
External reference voltage
If the Ref pin of the transducer is not used it could be either left unconnected or filtered according to the previous paragraph
“Reference V REF ”.
The Ref pin has two modes Ref IN and Ref OUT:
● In the Ref OUT mode the 2.5 V internal precision reference is used by the transducer as the reference point for bipolar
measurements; this internal reference is connected to the Ref pin of the transducer through a 680 Ohms resistor. it tolerates
sink or source currents up to ± 5 mA, but the 680 Ohms resistor prevents this current to exceed these limits.
● In the Ref IN mode, an external reference voltage is connected to the Ref pin; this voltage is specified in the range 0 to 4 V
and is directly used by the transducer as the reference point for measurements.
The external reference voltage V REF must be able:
- either to source a typical current of
Vref ? 2.5
680
, the maximum value will be 2.2 mA typ. when V REF = 4 V.
- or to sink a typical current of
2 . 5 ? Vref
680
, the maximum value will be 3.68 mA typ. when V REF = 0 V.
The following graphs show how the measuring range of each transducer version depends on the external reference voltage
value V REF .
