DIGITAL CHARACTERISTICS

POWER AND THERMAL CHARACTERISTICS

Notes:

11. Current consumption increases with increasing FS and increasing MCLK. Typ and Max values are

based on highest FS and highest MCLK. Variance between speed modes is small.

12. IL measured with no external loading on pin 8 (SDA).

13. Power-Down Mode is defined as RES pin = Low with all clock and data lines held static.

14. Valid with the recommended capacitor values on VQ and VBIAS as shown in the typical connection dia-

gram in Section 3.
