DRV601EVM Performance
Figure 19. Phase Response
The low-frequency cutoff of 10 Hz (–3 dB) is determined by the input ac-coupling capacitor, 1 µ F, together
with the feedback network input impedance of 15kR.
The low-pass, second-order filter implemented gives a –3 dB approximately at 35 kHz, and the response
is 13 dB down at 80 kHz.
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 ).
