DRV601EVM Performance
Figure 8. THD+N vs Voltage (100-k
Ω
load)
The THD+N in the range from 10mVrms to 1Vrms is completely dominated by noise.
Figure 9. THD+N vs Voltage (100-
Ω
load) Linear Scale
Here the THD+N versus output voltage is shown with linear scale; this makes it easier to see where
clipping occurs. Clipping is often defines as THD+N = 1%. For the DRV601 this is over 2.25 Vrms with a
3.3-V supply and 100-k
clipping occurs. Clipping is often defines as THD+N = 1%. For the DRV601 this is over 2.25 Vrms with a
3.3-V supply and 100-k
