Notes:
3. V_FS is tested under load R_L and includes attenuation due to Z_OUT
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. I_LC 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 5 and 6.
