6. Absolute Maximum Ratings
(VSS1 = VSS2 = 0 V; Note 4, Note 5)
Parameter Symbol Min. Max. Unit
Power Analog AVDD −0.3 4.3 V Supplies Digital I/F & LDO TVDD −0.3 4.3 V Input Current, Any Pin Except Supplies IIN - ± 10 mA Analog Input Voltage (Note 6) VINA −0.3 4.3 V TVDD + 0.3 Digital Input Voltage (Note 7) VIND1 −0.3 V or 4.3 AVDD + 0.3 (Note 8) VIND2 −0.3 V or 4.3 Ambient Temperature (power applied) Ta −40 85 C Storage Temperature Tstg −65 150 C Note 4. All voltages are with respect to ground. Note 5.
VSS1 and VSS2 must be connected to the same analog ground plane.
Note 6. AAAIN, AIN1P, AIN1N, AIN2P and AIN2N pins Note 7. EXTTRIG, MCKI, BCLK, LRCK, TDMIN, SYNCTRIG, I2CSEL, CSN/CAD, SCLK/SCL, SDA, SI, SID, DCSI, PDN and TEST pins; The maximum value is the lower of “TVDD + 0.3 V” and “4.3 V”. Note 8. DMDAT1 and DMDAT2 pins; The maximum value is the lower of “AVDD + 0.3 V” and “4.3 V”. WARNING: Operation beyond these limits may result in permanent damage to the device. Normal operation is not guaranteed at these extremes.
7. Recommended Operating Conditions
(VSS1 = VSS2 = 0 V; Note 9)
