Notes:

4. Current consumption increases with increasing Fs within a given speed mode and is signal dependent.

Max values are based on highest Fs and highest MCLK.

5. ILC measured with no external loading on the SDA pin.

6. Power-Down Mode is defined as RST pin = Low with all clock and data lines held static.

7. Valid with the recommended capacitor values on FILT+ and VQ as shown in Figures 7 and 8.
