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.
