10 / 76 page  ASAHI KASEI [AK4640] MS0273-E-00 2004/03 - 10 - ABSOLUTE MAXIMUM RATINGS (AVSS, DVSS, PVSS, HVSS=0V; Note 1) Parameter Symbol min max Units Power Supplies: Analog AVDD −0.3 4.6 V Digital DVDD −0.3 4.6 V PLL PVDD −0.3 4.6 V Headphone-Amp / Speaker-Amp HVDD −0.3 4.6 V |AVSS – PVSS| (Note 2) ∆GND1 - 0.3 V |AVSS – DVSS| (Note 2) ∆GND2 - 0.3 V |AVSS – HVSS| (Note 2) ∆GND3 - 0.3 V Input Current, Any Pin Except Supplies IIN - ±10 mA Analog Input Voltage VINA −0.3 AVDD+0.3 V Digital Input Voltage VIND −0.3 DVDD+0.3 V Ambient Temperature (powered applied) Ta −10 70 °C Storage Temperature Tstg −65 150 °C Note 1. All voltages with respect to ground. Note 2. AVSS, DVSS, PVSS and HVSS must be connected to the same analog ground plane. WARNING: Operation at or beyond these limits may result in permanent damage to the device. Normal operation is not guaranteed at these extremes. RECOMMENDED OPERATING CONDITIONS (AVSS, DVSS, PVSS, HVSS=0V; Note 1) Parameter Symbol min typ max Units Power Supplies Analog AVDD 2.4 3.3 3.6 V (Note 3) Digital DVDD 2.4 3.3 AVDD V PLL PVDD 2.4 3.3 AVDD V HP / SPK-Amp HVDD 2.4 3.3 3.6 V Note 1. All voltages with respect to ground. Note 3. The power up sequence between AVDD, DVDD, HVDD and PVDD is not critical. When the voltage difference among DVDD, PVDD and AVDD is larger than 0.3V, the power supply current at power down mode increases (see Note 19). When the power supplies are partially powered OFF, the AK4640 must be reset by bringing PDN pin “L” after these power supplies are powered ON again. * AKM assumes no responsibility for the usage beyond the conditions in this datasheet. |
