(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) Typical values represent most likely parametric norms at T_A = +25ºC, and at the Recommended Operation Conditions at the time of
product characterization and are not ensured.
(3) Datasheet min/max specification limits are ensured by test or statistical analysis.
(4) PSRR is measured as follows: V_OS is measured at two supply voltages, ±5V and ±15V, PSRR = |20log(ΔV_OS/ΔV_S)|.
