SDIN = 0. AOUT_REF input test signal is a 60 Hz, 50 mVpp sine wave. Measured by applying the test

signal into the AOUT_REF pin and measuring the resulting output amplitude on the AOUTx pin. Spec-

ification calculated by:

10. Applying a DC voltage on the AOUT_REF pin will cause a DC offset on the DAC output. See Section

4.1.3 for more information.

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.

Notes: 11. Response is clock-dependent and will scale with Fs.

12. For Single- and 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.

13. De-emphasis is available only in Single-Speed Mode.

14. Amplitude vs. Frequency plots of this data are available in “Digital Filter Response Plots” on page 21.
