Charge pump 1 & 2 are not in operation. In the case that charge pump 1 & 2 are in operation, the maximum values of AVDD and CVDD become 2.15 V. Note 7. All voltages with respect to ground. Note 8. VSS1, VSS2, VSS3 and VSS4 must be connected to the same analog plane. Note 9. XTI pin The maximum value of input voltage is lower value between (AVDD + 0.3) V and 4.3 V. Note 10. MCKI, BCLK, LRCK, SDATA, SCL, SDA, PDN, TESTI1, TESTI2 pins The maximum value of input voltage is lower value between (TVDD + 0.3) V and 4.3 V. WARNING: Operation at or beyond these limits may result in permanent damage to the device. Normal Operation is not guranteed at these extremes. 7.
