MAGNETIC RANGE CHARACTERISTICS

−40°C ≤ TA ≤ +125°C, supply voltage (VDD) = 4.5 V to 5.5 V, and the VOUT pin has a 1 kΩ resistor load (ROUT) with a 1 nF capacitor load

(COUT) to GND. The output voltage (VOUT) is taken between the ROUT and COUT components. The VOUT common mode is set to VSET/2, where

VSET is the voltage on the VSET pin and is tied to VDD, unless otherwise stated.

1 Ideal sensitivity, factory trimmed and calculated with the linear best-fit, is measured from the following points: ±2 mT, ±1 mT, and ±0.5 mT.

2 Production tested at ±1 mT. Full range guaranteed by design and/or characterization.

3 Ideal coefficient, factory trimmed and calculated with the third-order best-fit, is measured from the following points: ±2 mT, ±1 mT, and ±0.5 mT.
