ADC_FILT+ Capacitor Effects on THD+N
The value of the capacitor on the ADC_FILT+ pin, 16, affects the low frequency total harmonic distortion +
noise (THD+N) performance of the ADC. Larger capacitor values yield significant improvement in THD+N
at low frequencies.
Figure 32
shows the THD+N versus frequency for the ADC analog input. Plots were tak-
en from the CDB42L51 using an Audio Precision analyzer.
