Notes: 8. Normal operation is defined as RST = HI with a 997 Hz, 0 dBFS input sampled at the highest Fs for
each speed mode, and open outputs, unless otherwise specified.
9. Power Down Mode is defined as RST = LO with all clocks and data lines held static.
10. Valid with the recommended capacitor values on FILT+ and VQ as shown in Figure 14. Increasing the
capacitance will also increase the PSRR.
