Capacitor Size on the Reference Pin (FILT+)
The CS5341 requires an external capacitance on the internal reference voltage pin, FILT+. The size of this
decoupling capacitor will affect the low frequency distortion performance as shown in
capacitor values used to optimize low frequency distortion performance. This plot was taken using the
CDB5341 evaluation platform, with the device running in Single-Speed Mode and VA=VD=VL=5 V.
