Note1)
The electrical characteristics are numeric values within 3σ(99.7%) confirmed during product development.
Note2)
The characteristic items of *1 are adjusted values at the time of factory shipment.
Note3)
The offset voltage is a value after core demagnetization.
Note4)
The temperature coefficients indicate values obtained by dividing the maximum fluctuation in the operating temperature range by the temperature range.
Note5)
The output specifications are as follows; Vout output resistance: 2Ω(TYP), Vref output resistance: 200Ω(TYP), maximum output current: ±2mA, maximum load capacity: 100pF.
Note6)
The accuracies of *2 can be calculated by the following formula; accuracy at 25℃+(sensitivity temperature coefficient/10000×(Ta−25)+offset voltage temperature coefficient/800×100×(Ta−25)).
Note7)
The accuracies of *2 are values derived with reference to the internal reference output (Vref). Note that the internal reference voltage error and internal reference voltage temperature coefficient are added for accuracy when the internal reference voltage is not used.
Note8)
The above is for non-ratiometric specifications. Contact us separately if you require ratiometric specifications.
Note9)
Note that the output may fluctuate if the product is stored in a high-humidity environment.
