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 kΩ, C
L
= 10 pF (see Figure 2); “Required Initialization Settings” on
page 32 written on power up.
COMBINED DAC INTERPOLATION & ON-CHIP ANALOG FILTER RESPONSE
9. Response is clock dependent and will scale with Fs. Note that the response plots (Figures 22 and 25 on
page 63) have been normalized to Fs and can be de-normalized by multiplying the X-axis scale by Fs.
10. Measurement Bandwidth is from Stopband to 3 Fs.
