Hello,

    I'm still needing a low-pass filter for an audio application that I
could control with a PIC.

    I've tried to find MAX29X parts, but with no sucess. Even Maxim doesn't
have this parts in stock so I couldn't buy it.

    Someone can give me a circuit of a low-pass filter that could be
controled with a clock, like the MAX29X, or with a 0-5V voltage, like a VCF?

    The filter have to cut from about 200Hz to 4000Hz.

    Thank you very much,

    Brusque
