Notes: 9. Typical data is at T A = +25°C, V
DD
= 1.8V.
10. Maximum and minimum parameters values over 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.
