POWER AND THERMAL CHARACTERISTICS

Notes: 11. Current consumption increases with increasing FS and increasing MCLK. Variance between speed

modesissmall.

12. VD current consumption increases (ID normal and ID_pdn) when VD - VL > 1.5V. When VD - VL = 1.7V,

13. Power down mode is defined as RST pin = Low with clocks running.
