POWER AND THERMAL CHARACTERISTICS
Notes:
4. Current consumption increases with increasing Fs within a given speed mode and is signal dependent.
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 7 and 8 .
