2.9 Digital Characteristics
2.10 Power and Thermal Characteristics
Notes: 16. 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.
17. I
LS
measured with no external loading on pin 7 (RMCK).
18. I
LC
measured with no external loading on pin 2 (SDA).
19. Power-down mode is defined as RST pin = Low with all clock and data lines held static.
20. Valid with the recommended capacitor values on VFILT, VQ, and VBIAS+ as shown in the typical con-
nection diagram in Figure 10 .
