Figure 14. Pop/Click (Enable)
The DRV600 shows very low pop interference during the enable time; only two small, high-frequency
spikes can be seen.
No input signal is applied. The measurement results are presented both in a time domain and in a
frequency domain.
The resistive load is 600 Ω in both examples.
Figure 15. Pop/Click (Disable)
During power-down, the click is even lower than during power-on (enable). A very small click is seen.
Table 7 contains a list of documents that have a detailed description of the integrated circuits used in the
design of the DRV600EVM. The data sheet can be obtained through the TI website .
