DC ELECTRICAL CHARACTERISTICS
GND = GNDH = 0 V; all voltages with respect to ground. MCLK1=12.288 MHz; MCLK2=static; Fs=48 kHz; Master
Mode.
Notes: 13. Power-Down Mode is defined as RST = Low, with all clock and data lines held static low and no analog
input.
14. 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.
15. The DC current draw represents the allowed current draw due to typical leakage through the electrolytic
de-coupling capacitors.
DIGITAL INTERFACE CHARACTERISTICS
Note:
16. Digital Interface signals include all pins sourced from the VL supply as shown in “I/O Power Rails” on
page 12.
