POWER AND THERMAL CHARACTERISTICS
Notes: 11. Current consumption increases with increasing FS and increasing MCLK. Variance between speed
modes is small.
12. VD current consumption increases (ID normal and ID_pdn) when VD - VL > 1.5V. When VD - VL = 1.7V,
I
D
typically increases by 2 mA and when VD - VL = 2V, I
D
typically increases by 12 mA.
13. Power down mode is defined as RST pin = Low with clocks running.
DIGITAL CHARACTERISTICS
