4.1.3 AC/DC Characteristics
AC/DC characteristics involve the spread of values guaranteed within the specified voltage and
ambient temperature range. Typical characteristics are the median of the production. The device
performance paramter marked with x are not part of the production test, but were either verified by
design or measured in an Infineon Evalboard as described in Section 4-2.
