8 / 82 page  ASAHI KASEI [AK4633] MS0447-E-03 2006/04 - 8 - Handling of Unused Pin The unused I/O pins should be processed appropriately as below. Classification Pin Name Setting Analog MIC/MICP, BEEP/MICN, MPI, AOUT, SPP, SPN, VCOC These pins should be open. MCKI, SDTI These pins should be connected to DVSS. FCK, BICK (Note) These pins should be connected to DVSS, or should be pulled-down/pulled-up by about 100k Ω resister . Digital MCKO, SDTO These pins should be open. (Note) When the AK4633 is used by the slave mode (M/Sbit= “0”), these pins should be connected to DVSS. When the AK4633 is used by the master mode (M/Sbit= “1”), these pins should be pulled-down or pulled-up by about 100kΩ resistor. ABSOLUATE MAXIMUM RATING (AVSS, DVSS, SVSS=0V; Note 2) Parameter Symbol min max Units Power Supplies: Analog Digital Speaker-Amp |AVSS – DVSS| (Note 3) |AVSS – SVSS| (Note 3) AVDD DVDD SVDD ∆GND1 ∆GND2 −0.3 −0.3 −0.3 - - 4.6 4.6 4.6 0.3 0.3 V V V V 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 DVDD+0.3 V Ambient Temperature (powered applied) Ta −40 85 °C Storage Temperature Tstg −65 150 °C Maximum Power Dissipation (Note 4) Pd - 650 mW Note 2. All voltages with respect to ground. Note 3. AVSS, DVSS and SVSS must be connected to the same analog ground plane. Note 4. In case that PCB wiring density is 100%. This power is the AK4633 internal dissipation that does not include power of externally connected speaker. Note 5. BEEP/MICN, MIC/MICP pins Note 6. PDN, CSN, CCLK, CDTI, SDTI, FCK, BICK, MCKI pins WARNING: Operation at or beyond these limits may result in permanent damage to the device. Normal operation is not guaranteed at these extremes. |
