23. Power-Down Mode is defines as RESET = Low with all clock and data lines held static and no analog
input.
24. Valid with the recommended capacitor values on FILT1+, FILT2+, VQ1 and VQ2 as shown in the Typ-
ical Connection Diagram.
25. Guaranteed by design. The DC current draw represents the allowed current draw due to typical leakage
through the electrolytic de-coupling capacitors.
