(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur, including inoperability and degradation of
device reliability and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or
other conditions beyond those indicated in the Recommended Operating Conditions is not implied. The Recommended Operating
Conditions indicate conditions at which the device is functional and the device should not be operated beyond such conditions. All
voltages are measured with respect to the ground pin, unless otherwise specified.
(2) 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.
(3) 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.
(4) Datasheet min/max specification limits are specified by test or statistical analysis.
(5) PSRR is measured as follows: V_OS is measured at two supply voltages, ±5V and ±15V. PSRR = | 20log(ΔV_OS/ΔV_S) |.
