Notes:
4. VFS is tested under load RL and includes attenuation due to ZOUT
5. 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.
6. ILC measured with no external loading on the SDA pin.
7. This specification is violated when the VLC supply is greater than VD and when pin 16 (M1/SDA) is tied
or pulled low. Logic tied to pin 16 needs to be able to sink this current.
8. Power Down Mode is defined as RST pin = Low with all clock and data lines held static.
9. Valid with the recommended capacitor values on FILT+ and VQ as shown in Figures 5 and 6.
