Notes: 14. Current consumption increases with increasing Fs within the range of a speed mode. Variance between
speed modes is small. Typ and Max values are based on Fs = 48 kHz.
15. I_LC measured with no external loading on pin 2 (SDA).
16. Power-down mode is defined as RST pin = Low with all clock and data lines held static.
17. Valid with the recommended capacitor values on VFILT, VQ, and VBIAS+ as shown in the typical con-
nection diagram in Figure 10.
