DC ELECTRICAL CHARACTERISTICS

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

DIGITAL INPUT CHARACTERISTICS

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

DIGITAL INTERFACE SPECIFICATIONS

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

12. Normal operation is defined as RST = HI with a 997 Hz, 0dBFS input sampled at the highest F

s

for each

speed mode, and open outputs, unless otherwise specified.

13. Power Down Mode is defined as RST = LO with all clocks and data lines held static.
14. Valid with the recommended capacitor values on FILT+ and VQ as shown in Figure 1. Increasing the

capacitance will also increase the PSRR.
