Figures 3 through 5 show typical THD+N performance for CS4350 devices that exhibit the maximum full scale out-
put voltages as specified in the DAC Analog Characteristics tables (see
THD+N performance is increasingly affected by the full scale output voltage and temperature, with higher full scale
output voltage and lower temperatures corresponding to lower THD+N performance.
