Dear ADI,

Now we met a noise issue during our designing with ADAU1761, we need to creat a low cut filter(<30Hz) and a high pass filter(>25KHz) by ADAU1761 with 40dB attenuation at least.Do we have to design four normal series filters? Or is there a better scheme?  Are there some documents about ADAU dsp for common nosie issue?
