wave which fades from -60 to -120 dBFs. Dur-
ing the fade, the output from the CS4330/31/33
is measured and compared to the ideal level. No-
tice the very close tracking of the output level to
the ideal, even at low level inputs. This indicates
very good low-level linearity, one of the key
benefits of delta-sigma digital-to-analog conver-
sion.
