The unused I/O pin must be processed appropriately as below.
(VSS1=VSS2=0V;
Note 2. All voltages with respect to ground.
Note 3. VSS1 and VSS2 must be connected to the same analog ground plane.
Note 4. AINL+, AINL-, AINR+ and AINR- pins
Note 5. P/S, MCLK, LRCK, BICK, SDTI, CDTI/CKS0, CCLK/CKS1, CSN/DIF, DFS0, PDN, DEM0 and SDFIL pins.
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
(VSS1=VSS2=0V;
Note 2. All voltages with respect to ground.
Note 6: The power up sequence among AVDD, DVDD and TVDD is not critical.
WARNING: AKM assumes no responsibility for the usage beyond the conditions in this datasheet.
