Notes: 9. Typical data is at T
A
= +25°C, V
DD
= 3V, and for design information only.
10. Maximum and minimum parameters values over the operating temperature range are not tested in production, they are guaranteed by design,
characterization and process control. The magnetic characteristics may vary with supply voltage, operating temperature and after soldering.
11. Maximum and minimum hysteresis is guaranteed by design and characterization.
