Note 1: Over operating free-air temperature range unless oth-
erwise noted.
Note 2: All voltage values are with respect to the ground termi-
nal, pin 8.
Note 3: The reference regulator may be bypassed for operation
from a fixed 5V supply by connecting the V
CC
and ref-
erence output pins both to the supply voltage. In this
configuration the maximum supply voltage is 6V
Note 4: Consult packaging section of databook for thermal lim-
itations and considerations of package.
