Description
This addendum adds various features and parameters to the
general sales datasheet (A1190, A1192 and A1193) for these
devices, to adapt the A1192 and A1193 for use with ferrite
magnets.
For parameters not listed in this addendum, refer to the general sales datasheet. In the event of a conflict between this
addendum and the general sales datasheet, this addendum
takes precedence.
