Note 1: Maximum package power dissipation limits must be observed.

Note 2: Low duty cycle pulse techniques are used during test to maintain

junction temperature as close to ambient as possible:

Note 4: Comparator gain is defined as:

AV=

Note 5: These parameters are guaranteed by design but not 100% tested

in production.
