COMBINED INTERPOLATION & ON-CHIP ANALOG FILTER RESPONSE
(The filter characteristics have been normalized to the sample rate (Fs) and can be referenced to the desired sam-
ple rate by multiplying the given characteristic by Fs. Amplitude vs. frequency plots of the data in the table below
are available in “Digital Filter Response Plots” on page 16.)
Notes:
3. Response is clock-dependent and will scale with Fs.
4. For Single-Speed Mode, the Measurement Bandwidth is from stopband to 3 Fs.
For Double-Speed Mode, the Measurement Bandwidth is from stopband to 3 Fs.
For Quad-Speed Mode, the Measurement Bandwidth is from stopband to 1.34 Fs.
5. De-emphasis is available only in Single-Speed Mode.

DIGITAL CHARACTERISTICS
POWER AND THERMAL CHARACTERISTICS
Notes:
6. Current consumption increases with increasing FS and increasing MCLK. Typ and Max values are
based on highest FS and highest MCLK. Variance between speed modes is small.
7. Power down mode is defined as RST
pin = Low with all clock and data lines held static low. All digital
inputs have a weak pull-down which is only present during reset. Opposing this pull-down will slightly
increase the power-down current (pull-down is equivalent to a 50 kΩ resistor per pin).
8. Valid with the recommended capacitor values on VQ and V
BIAS
as shown in the typical connection dia-
gram in Section 3.
