DC ELECTRICAL CHARACTERISTICS
Test conditions (unless otherwise specified): VA = 5 V, VL = 3.3 V; GND = 0 V; SDIN = 0; all voltages with respect
to ground.
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
page 8. Variance 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.

Digital I/O Pin Characteristics
Input and output levels and associated typical power supply voltage are shown in
Table 2. Logic levels
should not exceed the corresponding power supply voltage.
