Reference voltage
The Ref pin has two modes Ref IN and Ref OUT.
＜ Ref OUT mode ＞
Introduction

The 2.5 V internal precision reference is used by the transducer as the reference point for bipolar measurements.
＜ Ref IN mode ＞
An external reference voltage is connected to the Ref pin. this voltage is specified in the range 0 to 4 V.
its voltage is used as the reference voltage at the time of measurement.
-either to source a typical current of (Vref2-2.5)/680,the maximum value will be 2.2 mA typ.when Vref2 ＝ 4 V.
-or to sink a typical current of (2.5-Vref2)/680,the maximum value will be 3.68 mA typ.when Vref2 ＝ 0 V.

RL=1 k Ω , Vcc=+5 V, TA=-40 ～ +85 ℃

The following graphs show how the measuring range of each transducer version depends on external reference voltage value Vref2.
