LINE OUTPUT VOLTAGE LEVEL CHARACTERISTICS

Test conditions (unless otherwise specified): Input test signal is a full-scale 997 Hz sine wave; measurement bandwidth is 20 Hz
to 20 kHz; Sample Frequency = 48 kHz; Test load R

L

= 10 k

 C

L

= 10 pF (see

COMBINED DAC INTERPOLATION AND ONCHIP ANALOG FILTER RESPONSE

12. Response is clock dependent and scales with Fs. Note that the response plots (

Figures 30

and

33 on

page 78

) have been normalized to Fs and can be de-normalized by multiplying the X-axis scale by Fs.

13. Measurement Bandwidth is from Stopband to 3 Fs.
