Power Supply Current
normal operation, VA= 5 V
(Note 4)
(Note 5) Interface current, VLC=5 V
Notes:
3.
V
FS
is tested under load R
L
and includes attenuation due to Z
OUT
4.
Current consumption increases with increasing FS within a given speed mode and is signal dependant.
Max values are based on highest FS and highest MCLK.
5.
I
LC
measured with no external loading on the SDA pin.
6.
Power down mode is defined as RST pin = Low with all clock and data lines held static.
7.
Valid with the recommended capacitor values on FILT+ and VQ as shown in Figures 5 and 6.
