DC ELECTRICAL CHARACTERISTICS
Test conditions (unless otherwise specified): VCP = VA = VL = 3.3 V; AGND = DGND = CPGND = 0 V; SDIN = 0;
all voltages with respect to ground.
Notes: 15. 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.
16. 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 k
) which is only present during reset. Opposing this pull-
down will slightly increase the power-down current.
17. Valid with the recommended capacitor value on VBIAS as shown in the typical connection diagram in
Section 3 .
18. Typical voltage shown for “Initialization State”; see Section 4.8 . 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 1 . Logic levels should not
exceed the corresponding power supply voltage.
