NOTES:1. Magnetic flux density is measured at most sensitive area of device,
nominally located 0.0165” (0.42 mm) below the branded face of the package.
2. Typical Data is at VCC = 12 V and TA = +25°C and is for design information only.
3. As used here, negative flux densities are defined as less than zero (algebraic convention).
