Measurement conditions: Except where noted otherwise, in measurement circuits VCC=1.2V
*1: At a certain point within the range VCC=1.0 to 5.0 V, IM=25 to 200 mA, the value of VA is varied and
the value VM/ VA is determined.
*2: At a certain point within the range VCC=1.0 to 5.0 V, the value of IM is varied between 25 mA and 225
mA, and the value VM/ IA is determined.
*3: The temperature characteristics of the reference voltage, output voltage and bridge ratio, as well as
the drift characteristic, are all reference values and are not guaranteed.
