11 G (gauss) = 0.1 mT (millitesla),  
2 On power-up, the output of the device is held low until VCC exceeds VUVLOHI. After the device is powered, the output remains valid until VCC drops  
below VUVLOLO , when the output is pulled low.  
3 Determined by design and characterization, not evaluated at final test.  
4 See the Characteristic Definitions section.  
5 fC varies as much as approximately ±20% across the full operating ambient temperature range and process.  
6 Output Referred Noise is calculated as 6 sigma (6 standard deviations) from characterization of a small sample of devices. Conversion of noise from  
gauss to mV(P-P) can be done by: Noise (G) × Sensitivity (mV/G) = Noise (mV(P-P)).  
7 VCLPLOW and VCLPHIGH scale with VCC due to ratiometry.  
8 Parameter is tested at wafer probe only.  
9 Percent change from actual value at VCC = 5 V, for a given temperature.  
10 Percent change from actual value at VCC = 5 V, TA = 25°C.  
11 Sensitivity drift through the life of the part, ΔSensLIFE, can have a typical error value ±3% in addition to package hysteresis effects.
