Notes:
22. Current consumption increases with increasing FS and increasing OMCK. Max values are based on
highest FS and highest OMCK. Variance between speed modes is negligible.
23. I_LC measured with no external loading on the SDA pin.
24. Power-Down Mode is defined as RST pin = Low with all clock and data lines held static.
25. Valid with the recommended capacitor values on FILT+ and VQ as shown in Figure 5.
