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. I
L
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 V
BIAS
as shown in the typical connection dia-
gram in Section 3 .
