¹1 G (gauss) = 0.1 mT (millitesla),

²On power-up, the output of the device is held low until V_CCexceeds V_UVLOHI. After the device is powered, the output remains valid until V_CCdrops

below V_UVLOLO, when the output is pulled low.

³See the Characteristic Definitions section.

⁴Determined by design and characterization, not evaluated at final test.

⁵f_Cvaries as much as approximately ±20% across the full operating ambient temperature range and process.
