Notes: 17. Power Down Mode is defines as RESET = Low with all clock and data lines held static and no analog
input.
18. Valid with the recommended capacitor values on FILT+ and VQ as shown in the Typical Connection
Diagram.
19. Guaranteed by design. The DC current draw represents the allowed current draw due to typical leakage
through the electrolytic de-coupling capacitors.
