(1) 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 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 I_SD by a maximum of 2µA. The
Shutdown pin should be driven as close as possible to GND for minimal shutdown current and to V_DD for the best THD performance in
PLAY mode. See the Application Information section under SHUTDOWN FUNCTION for more information.
