Notes: 4. V_FS is tested under load R_L and includes attenuation due to Z_OUT
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. I_LC 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.
