DIGITAL INPUT CHARACTERISTICS
7. I
in
for LRCK is ±20 A max.
POWER AND THERMAL CHARACTERISTICS
8. 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.
9. Power down mode is defined when all clock and data lines are held static.
10. Valid with the recommended capacitor values on VQ and FILT+
as shown in the typical connection di-
agram in Section 3 .
