DIGITAL INPUT CHARACTERISTICS
6. RST pin has an input threshold relative to VL, but is VA tolerant.
7. I
in
for LRCK is ±20
A max.
POWER & THERMAL CHARACTERISTICS
8. Current consumption increases with increasing FS and increasing MCLK. Typ and Max values are
based on highest FS and highest MCLK. Current 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 4 .
