DC ELECTRICAL CHARACTERISTICS

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

Notes: 13. Normal operation is defined as RST = HI with a 997 Hz, 0 dBFS input sampled at the highest F

s

for each

speed mode, and open outputs, unless otherwise specified.

14. I

LC

measured with no external loading on pin 12 (SDA).

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

16. Valid with the recommended capacitor values on FILT+ and VQ as shown in Figure 1. Increasing the

capacitance will also increase the PSRR.
