(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)

RL is a resistive load in series with two inductors to simulate an actual speaker load. For RL = 8Ω, the load is 15µH + 8Ω +15µH.

(4)

Typical values represent most likely parametric norms at TA = +25°C, and at the Recommended Operation Conditions at the time of

product characterization and are not ensured.

(5)

Datasheet min/max specification limits are ensured by test or statistical analysis.
