DRV601EVM Performance
Figure 10. THD+N vs Voltage (600-
Ω Load)
Here the clipping is shown with a 3.3-V supply, and
±
10% tolerance. It shows that even with a low DVDD,
3.3 V–10% , the DRV601 can achieve the 2 Vrms with a THD+N less than 1%.
2 Vrms is equal to 2.848-Vpeak; that is only 142-mV drop from the 2.97-V supply
Figure 11. THD+N vs Voltage (100-k
Ω
Load)
With the THD+N in dB scale. 0.001% corresponds to –100 dB.
