(1)

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

product characterization and are not specified.

(2)

Datasheet min/max specification limits are not specified by test or statistical analysis.

(3)

Shutdown current is measured in a normal room environment. Exposure to direct sunlight will increase ISD by a maximum of 2µA. The

Shutdown pin should be driven as close as possible to GND for minimal shutdown current and to VDD for the best THD performance in

PLAY mode. See the Application Information section under SHUTDOWN FUNCTION for more information.
