1 Maximum voltage must be adjusted for power dissipation and junction temperature, see Power Derating section.

2 For VCC slew rates greater than 250 V/μs, and TA = 150°C, the Power-On Time can reach its maximum value.

3 CS =oscilloscope probe capacitance.

4 Maximum current limit is equal to the maximum ICC(max) + 22 mA.

5 Magnetic flux density, B, is indicated as a negative value for north-polarity magnetic fields, and as a positive value for south-polarity magnetic fields.

This so-called algebraic convention supports arithmetic comparison of north and south polarity values, where the relative strength of the field is indicated

by the absolute value of B, and the sign indicates the polarity of the field (for example, a –100 G field and a 100 G field have equivalent strength, but

opposite polarity).
