DRV601EVM2 Performance
No input signal is applied. The measurement results are presented both in a time domain and in a
frequency domain. The resistor load is 600 Ω .
The power supply is applied, and then the shutdown signal is released. The shutdown signal is used to
trigger the measuring system. For a description of the measuring technique, see the application report
Pop and Click Measuring Technique (SLEA044 ).
Figure 20. Pop/Click (Enable)
The DRV601 shows low pop during enable; only two small high-frequency spikes can be seen. The
measurements are made with reference to 2 V
rms
= 0 dB, 2 mV=-60 dBr.
No input signal is applied. The measurement results are presented both in a time domain and in a
frequency domain.
No input signal applied. Load: 600 Ω .
