DC ELECTRICAL CHARACTERISTICS

(AGND = 0 V; all voltages with respect to AGND.)

Notes: 13. 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.

14. Power Down Mode is defined as RST = LO with all clocks and data lines held static.

15. Valid with the recommended capacitor values on FILT+ and VQ as shown in Figure 16. Increasing the

capacitance will also increase the PSRR.
