Note 1. All voltages are respect to ground. The PDN pin should be held to “L” when powered-up, and it should be set to
“H” after all power supplies are powered-up. The PDN pin should be held to “L”, when powered-down.
Note 2. VSS1 and VSS2 must be connected to the same analog plane.
Note 3. LIN, RIN and PDN pin
The maximum value is smaller value between (AVDD+0.3)V and 6.0V.
Note 4. PCB wiring density should be 150% or more. Device back PAD should be connected to ground.
Note 5. Headphone Output Power should below 65mW/ch.
Note 6. Headphone Output Power should below 50mW/ch.
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.
