7 / 105 page  [AK4636] MS1012-E-01 2010/08 - 7 - ■ Handling of Unused Pin The unused I/O pins must be processed appropriately as below. Classification Pin Name Setting Analog MIC/MICP, LIN/MICN, MPI, AOUT, SPP, SPN, VCOC, VIN, VOUT These pins must be open. MCKI, SDTI These pins must be connected to VSS2. CDTIO When I2C pin = “H”, These pins should be connected to VSS2. Digital MCKO, SDTO These pins must be open. ABSOLUTE MAXIMUM RATINGS (VSS=VSS2=VSS3=0V; Note 1) Parameter Symbol min max Units Power Supplies: Analog Digital Speaker-Amp Video-Amp AVDD DVDD SVDD VVDD −0.3 −0.3 −0.3 −0.3 4.6 4.6 4.6 4.6 V V V V Input Current, Any Pin Except Supplies IIN - ±10 mA Analog Input Voltage (Note 2) VINA −0.3 AVDD+0.3 V Digital Input Voltage (Note 3) VIND −0.3 DVDD+0.3 V Video-amp Input Voltage (Note 4) VINV −0.3 VVDD+0.3 V Ambient Temperature (powered applied) Ta −30 85 °C Storage Temperature Tstg −65 150 °C Maximum Power Dissipation (Note 5) Pd - 450 mW Note 1. All voltages with respect to ground. VSS21, VSS2 and VSS3 must be connected to the same analog ground plane. Note 2. LIN/MICN/DMCLK, MIC/MICP/DMDAT, BEEP pins Note 3. PDN, I2C, CSN/SDA, CCLK/SCL, CDTIO, SDTI, FCK, BICK, MCKI pins Pull-up resistors at SDA and SCL pins should be connected to (DVDD+0.3)V or less voltage. Note 4. VIN pin Note 5. AK4636ECB: When PCB wiring density is more than 200% and superficial layer writing density is more than 50%. AK4636EN: When PCB wiring density is more than 100%. This power is the AK4636 internal dissipation that does not include power of externally connected speakers. WARNING: Operation at or beyond these limits may result in permanent damage to the device. Normal operation is not guaranteed at these extremes. |
