Notes: 15. Power supply current 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.
16. During normal operation, SDIN = 997 Hz sine wave at 0 dBFS with load resistance RL = 3 k.
17. Power-down is defined as all clock and data lines held static low. All digital inputs have a weak pull-
down (approximately 50 k) which is only present during power on reset. Opposing this pull-down will
increase the power-down current.
18. Valid with the recommended capacitor values as shown in the typical connection diagram in Section 5.
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.
