8. Current consumption increases with increasing FS and increasing MCLK. Typ and Max values are

based on highest FS and highest MCLK. Current variance between speed modes is small.

9. Power-Down Mode is defined when all clock and data lines are held static.

10. Valid with the recommended capacitor values on VQ and FILT+ as shown in the typical connection di-

agram in Section 4.
