Have you one?

I need for use in a telephonic circuit, and it must have the telephonic band width, 300 to 3400 hz, 0 to -2.5 dB of attenuation, and for 100Hz it must be better than -30dB.

Thankz :D

Hi penrico,

i mean you should use some of the development soft for filters. Se at the www pages of LInear Technology or Maxim or other manufactors for filter IC's.

In the net you will find moch more of filter soft for your project.

Greetings from Germany

One of the best filter design programs is from nuhertz technologies.
They have a free download:

Hi there
I used twin T circuit for realizing notch at 300Hz for voice modem.
I suggest you to investigate to use it.

i agree with ptoo30 a twin T will cause less distortions than a chip
in the long run

and i think it will be much tighter... filter...
