ground. MCLK=12.288 MHz; Fs=48 kHz, Master Mode)

Notes: 9. Power Down Mode is defines as RESET = Low with all clock and data lines held static and no analog

input.

10. Valid with the recommended capacitor values on FILT+ and VQ as shown in the Typical Connection

Diagram.

11. Guaranteed by design. The DC current draw represents the allowed current draw due to typical leakage

through the electrolytic de-coupling capacitors.
