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

COMBINED DAC INTERPOLATION & ON-CHIP ANALOG FILTER RESPONSE
9.
Response is clock dependent and will scale with Fs. Note that the response plots (
and
) 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.
