ASAHI KASEI
The unused I/O pins should be processed appropriately as below.
(AVSS, DVSS, HVSS=0V; Note 2)
Note 2. All voltages with respect to ground
Note 3. AVSS, DVSS and HVSS must be connected to the same analog ground plane.
Note 4. MIN, RIN, LIN, MICIN, AINR1, AINL1 pins
Note 5. PDN, CSN, CCLK, CDTI, LRCK, MCLK, BICK, SDTI pins
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
(AVSS, DVSS, HVSS=0V; Note 2)
Note 2. All voltages with respect to ground
Note 6. If each power supply is gradually switched on or off, some supply current may occur at the other power supply
Note: AKM assumes no responsibility for usage beyond the conditions in this datasheet.
