6 / 99 page  [AK4953A] MS1252-E-05 2015/10 - 6 - ■ Handling of Unused Pin The unused I/O pins must be processed appropriately as below. Classification Pin Name Setting Analog MPWR1, MPWR2, SPN, SPP, HPL, HPR, CP, CN, PVEE, LIN1/DMDAT, RIN1/DMCLK, LIN2, RIN2, LIN3, RIN3 These pins must be open. Digital MCKO This pin must be open. MCKI This pin must be connected to VSS2. ABSOLUTE MAXIMUM RATINGS (VSS1=VSS2=VSS3=VSS4=0V; Note 3) Parameter Symbol Min. Max. Unit Power Supplies: Analog AVDD 0.3 6.0 V Digital DVDD 0.3 2.5 V Digital I/O TVDD 0.3 6.0 V Speaker-Amp SVDD 0.3 6.0 V Input Current, Any Pin Except Supplies IIN - 10 mA Analog Input Voltage (Note 5) VINA 0.3 AVDD+0.3 V Digital Input Voltage (Note 6) VIND 0.3 TVDD+0.3 V Ambient Temperature (powered applied) Ta 30 85 C Storage Temperature Tstg 65 150 C Maximum Power Dissipation (Note 7) Ta = 85C (Note 8) Pd1 - 660 mW Ta = 70C (Note 9) Pd2 - 900 mW Note 3. All voltages are with respect to ground. Note 4. VSS1, VSS2, VSS3 and VSS4 must be connected to the same analog ground plane. Note 5. LIN1, RIN1, LIN2, RIN2, LIN3, RIN3 pins Note 6. PDN, CSN, CCLK, CDTIO, SDTI, LRCK, BICK and MCKI pins Pull-up resistors at SDA and SCL pins should be connected to (TVDD+0.3)V or less voltage. Note 7. In case that PCB wiring density is 100% over. This power is the AK4953A internal dissipation that does not include power dissipation of externally connected speakers. Note 8. The Speaker Amplifier is not available. Note 9. The Speaker Amplifier is available. WARNING: Operation at or beyond these limits may result in permanent damage to the device. Normal operation is not guaranteed at these extremes. |
