5 / 31 page [AK4440] PIN/FUNCTION (Continued) No. Pin Name I/O Function 29 VSS2 - Ground Pin 30 VDD - Charge Pump and DAC Digital Power Supply Pin: 4.5V ∼5.5V Note: All input pins except for the P/S pin should not be left floating. ■ Handling of Unused Pin The following tables illustrate recommended states for open pins: Classification Pin Name Setting Analog LOUT4-1, ROUT4-1 Leave open. SDTI4-1 Connect to VSS2. Digital DEM0, TDM0B (Serial control mode) Connect to VDD or VSS2. TEST Leave open. ABSOLUTE MAXIMUM RATINGS (VSS1=VSS2=0V; Note 1) Parameter Symbol min max Units Power Supply VDD AVDD -0.3 -0.3 +6.0 +6.0 V V Input Current (any pins except supplies) IIN - ±10 mA Input Voltage VIND -0.3 VDD+0.3 V Ambient Operating Temperature Ta -20 85 °C Storage Temperature Tstg -65 150 °C Note 1. All voltages with respect to ground. Note 2. VSS1 and VSS2 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 (VSS1=VSS2=0V; Note 1) Parameter Symbol min typ max Units Power Supply VDD AVDD +4.5 +5.0 VDD +5.5 V Note 3. VDD and AVDD are the same voltage. *AKM assumes no responsibility for the usage beyond the conditions in this datasheet. MS1088-E-01 2011/03 - 5 - |
