Note 6. 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. Recommended Operating Conditions

Note 11. All voltages with respect to ground.
Note 12. Each power up/down sequence is shown below. 1. PDN pin = “L”
2. TVDD, AVDD, LVDD, CVDD
(AVDD must be powered up before or at the same time of CVDD. The power-up sequence of
TVDD and LVDD is not critical.)
3. The PDN pin is allowed to be “H” after all power supplies are applied and settled. 1. PDN pin = “L”
2. TVDD, AVDD, LVDD, CVDD
(CVDD must be powered down before or at the same time of AVDD. The power-down
sequence of TVDD and LVDD is not critical.) 018001092-E-00 2018/02
