Subjects (major changes since last revision)
This data sheet replaces the revision from 2009-12-04. The reason for the new revision is to increase
the information content for the circuit designer. The performance parameters are now enlisted in a
table containing many relevant application frequencies. The measurements of typical devices have
been repeated and the device description has been expanded by adding several new characteristic
curves. For customers who bought the product prior to the issue of the new revision the old
specifications remain valid.
