VMID
The analogue circuitry will not work when VMID is disabled (VMIDSEL[1:0] = 00b). The impedance of
the VMID resistor string, together with the decoupling capacitor on the VMID pin will determine the
startup time of the VMID circuit.

ESTIMATED SUPPLY CURRENTS
When either the DAC or ADC are enabled it is estimated that approximately 4mA will be drawn from
DCVDD when DCVDD=1.8V and fs=48kHz (This will be lower at lower sample rates). When the PLL
is enabled an additional 700 microamps will be drawn from DCVDD.
Table 45 shows the estimated 3.3V AVDD current drawn by various circuits, by register bit.
