Notes:

1. AVCC_DAC1/2 can change up to ±15% when using the ES9312Q Voltage Regulator in Calibration Mode. The

output voltage will change as the DAC’s output impedance changes. See ES9312Q Datasheet for more information.

Recommended Power Up/Down Sequence

The recommended power up sequence for the ES9039Q2M, the AVDD supply is enabled ~200us before VCCA. Finally

enable AVCC_DAC1/2 then the chip can be enabled.

Figure 18 – Recommended Power Up Sequence

On power down, after CHIP_EN is disabled, AVCC_DAC1/2 are disabled, followed by VCCA, then finally AVDD.
