DC ELECTRICAL CHARACTERISTICS
AGND = DGND = 0 V, all voltages with respect to ground. MCLK=12.288 MHz; Fs=48 kHz; Master Mode.
13. Power-Down Mode is defines as RESET
= Low with all clock and data lines he ld static and no analog
input.
14. Valid with the recommended capacitor values on FILT+ and VQ as shown in the Typical Connection
Diagram.
15. Guaranteed by design. The DC current draw represents the allowed current draw due to typical le akage
through the electrolytic de-coupling capacitors.
