Notes: 3. VFS is tested under load RL and includes attenuation due to ZOUT
4. Current consumption increases with increasing FS within a given speed mode and is signal dependant.
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.
