Note 1. All voltages are respect to ground.
Note 2. VSS1 and VSS2 must be connected to the same analog plane.
Note 3. LIN, RIN, PDN pin
The maximum value is low value either (AVDD+0.3) V or 6.0V.
Note 4. 2ch Output Power (Po, when load is 16Ω) should be less TBD W.
Note 5. The power up sequence among AVDD, PVDD is not critical. The PDN pin should be held to “L” when
powered-up. The PDN pin should be set to “H” after all power supplies are powered-up. The PDN pin should be
held to “L”, when powered-down. Operation by the power-supply voltage from 3.6 to 4.5V is prohibited.
Note: AKEMD assumes no responsibility for the usage beyond the conditions in this datasheet.
