1) Stress above one or more of the limiting values may cause permanent damage to the device. Exposure to limiting
values for extended periods may affect device reliability.
2) The sensitivity is defined as the average slope of characteristic between Hy=0 and 6 kA/m and Hx=3kA/m:
3) Hysteresis is defined as the difference between offset voltages measured without Hy-field after premagnetization by
negative and positive Hy=±6 kA/m field:
4) The linearity error is the deviation of output voltage measured at Hy=3 kA/m from the average of Hy=0 and 6 kA/m- output
voltages, expressed as percentage of the output voltage difference measured between 0 and 6 kA/m:
5) The temperature coefficient of sensitivity is defined as the percentage change of the sensitivity per K referred to the value
at T1 = -25 °C; T2= operating temperature:
