(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
Conditionsindicate 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) If Military/Aerospace specified devices are required, please contact the TI Sales Office/ Distributors for availability and specifications.
(4) The maximum power dissipation must be derated at elevated temperatures and is dictated by T
JMAX
, θ

, and the ambient temperature,
T

(2) R
L
is a resistive load in series with two inductors to simulate an actual speaker load. For R
L
= 8Ω, the load is 15µH + 8Ω, +15µH. For R
L
= 4Ω, the load is 15µH + 4Ω + 15µH.
(3) Typical values represent most likely parametric norms at T
A
= +25°C, and at the Recommended Operation Conditions at the time of
product characterization and are not specified.
(4) Datasheet min/max specification limits are specified by test or statistical analysis.
