Notes: 13. Current consumption increases with increasing sample rate and increasing MCLK frequency. Typical
values are based on Fs = 48 kHz and MCLK = 12.288 MHz. Maximum values are based on highest
sample rate and highest MCLK frequency; see Switching Specifications - Serial Audio Interface. Vari-
ance between speed modes is small.
14. Power-down is defined as RESET pin = Low with all clock and data lines held static low. All digital inputs
have a weak pull-down (approximately 50 kΩ) which is only present during reset. Opposing this pull-
down will slightly increase the power-down current.
15. Valid with the recommended capacitor value on VBIAS as shown in the typical connection diagram in
Section 3.
16. Typical voltage shown for “Initialization State”, see Section 4.7. Typical voltage may be up to 1.5 V lower
during normal operation.
2.1 Digital I/O Pin Characteristics
Input and output levels and associated power supply voltage are shown in Table 2. Logic levels should not
exceed the corresponding power supply voltage.
