DC ELECTRICAL CHARACTERISTICS
(AGND = DGND = 0 V, all voltages with respect to
ground. MCLK=12.288 MHz; Fs=48 kHz, Master Mode)
Notes: 20. Power Down Mode is defines as RESET = Low with all clock and data lines held static and no analog
input.
21. Valid with the recommended capacitor values on FILT1+, FILT2+, VQ1 and VQ2 as shown in the
Typical Connection Diagram.
22. Guaranteed by design. The DC current draw represents the allowed current draw due to typical leakage
through the electrolytic de-coupling capacitors.
