(1) The electrical Characteristics tables list ensured specifications under the listed Recommended Operating Conditions except as otherwise
modified or specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations only and are not
ensured.
(2) Datasheet min/max specification limits are ensured by test.
(3) Typical values represent the most likely parameter norms at T
A
= +25°C, and at the Recommended Operation Conditions at the time of
product characterization and are not ensured.
(4) Both the gain of the preamplifier A1
V
and the gain of the buffer amplifier A2
V
are measured individually. The over all gain of both
amplifiers A
V
is also measured to assure the gain of all parts is always within the A
V
limits.
(5) Slew rate is the average of the rising and falling slew rates.
(6) Offset voltage drift determined by dividing the change in V
OS
at temperature extremes into the total temperature change.
