POWER AND THERMAL CHARACTERISTICS
Notes:
6.
Current consumption increases with increasing FS and increasing MCLK. Typ and Max values are
based on highest FS and highest MCLK. Variance between speed modes is small.
7.
Power down mode is defined as RST pin = Low with all clock and data lines held static low. All digital
inputs have a weak pull-down which is only present during reset. Opposing this pull-down will slightly
increase the power-down current (pull-down is equivalent to a 50 k
Ω resistor per pin).
8.
Valid with the recommended capacitor values on VQ and V
