Note 1: All devices are 100% production tested at T
A
= +25°C; all specifications over temperature are guaranteed by design,
unless otherwise specified.
Note 2: Guaranteed by design, not production tested.
Note 3: Maxim specification limits for the temperature coefficient of the offset voltage (TCV
OS
) are 100% tested for the A-grade, 8-
pin SO and µMAX packages.
