Notes: 24. Normal operation is defined as RST = HI with a 997 Hz, 0 dBFS input to the DAC and AUX port, and a
1 kHz, -1 dB analog input to the ADC port sampled at the highest F for each speed mode. DAC outputs
s
are open, unless otherwise specified.
25. I measured with no external loading on pin 2 (SDA).
DT
26. Valid with the recommended capacitor values on FILT+ and VQ. Increasing the capacitance will also
increase the PSRR.
27. Power Down Mode is defined as RST = LO with all clocks and data lines held static and no analog input.
28. Guaranteed by design. The DC current draw represents the allowed current draw from the VQ pin due
to typical leakage through the electrolytic de-coupling capacitors.
