(1) The algebraic convention, whereby the most negative value is a minimum and the most positive value is a maximum.
(2) Parts are tested at 85 ° C and specified by design and correlation over the full temperature range.
(3) Typical values are at T

as measured over the specified analog signal
ranges.
(6) Leakage parameters are 100% tested at the maximum-rated hot operating temperature and specified by correlation at T
