Notes: 14. Power-Down Mode is defined as RST = Low, with all clock and data lines held static low and no analog
input.
15. Valid with the recommended capacitor values on FILT+, VCMDAC, VCMADC and VCMBUF as shown
in Figure 7 on page 26 and Figure 8 on page 27.
16. The DC current draw represents the allowed current draw due to typical leakage through the electrolytic
de-coupling capacitors.
