The component values can be calculated with the help of the TI FilterPro
program available on the TI website
at:
Figure 49. Second-Order Active Low-Pass Filter
The resistor values should have a low value for obtaining low noise, but should also have a high enough value to
get a small size ac-coupling cap. C2 can be split in two with the midpoint connected to GND, this can increase
the common-mode attenuation.
Pop-Free Power Up
Pop-free power up is ensured by keeping the HP_SD low during power supply ramp up and down. The pin
should be kept low until the input AC-coupling capacitors are fully charged before asserting the HP_SD pin high,
this way proper pre-charge of the ac-coupling is performed and pop-less power-up is achieved. Figure 50
illustrates the preferred sequence.
