DC ELECTRICAL CHARACTERISTICS
(AGND = 0V; all voltages with respect to AGND.)
Notes: 10. Normal operation is defined as RST = HI with a 997 Hz, 0dBFS input sampled at F
s
= 48kHz, and open
outputs, unless otherwise stated.
11. Power-Down Mode is defined as RST = LO with all clocks and data lines held static.
12. Valid with the recommended capacitor values on FILT+ and VQ as shown in Figures 1 and 2.
