ANALOG CHARACTERISTICS

POWER AND THERMAL CHARACTERISTICS

Notes:

4. V

is tested under load R

and includes attenuation due to Z

OUT

5. 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.

6. I

measured with no external loading on the SDA pin.

7. This specification is violated when the VLC supply is greater than VD and when pin 16 (M1/SDA) is tied

or pulled low. Logic tied to pin 16 needs to be able to sink this current.

8. Power Down Mode is defined as RST

pin = Low with all clock and data lines held static.

9. Valid with the recommended capacitor values on FILT+ and VQ as shown in Figures 5 and 6.
