Product details

Description

The LMF120 is a mask-programmable switched-capacitor filter capable of realizing virtually any filter response up to twelve poles using six independent biquad blocks.

Features

Mask-programmable for virtually any filter response.
All filter types (low-pass, high-pass, bandpass, notch, all-pass).
All filter approximations (Butterworth, Chebyshev, Ellip- tic, Bessel, etc. ).
Up to 12 poles and right-half-plane zeros in one 16-pin package.
One, two, or three filters per package.
Wide Q range: up to 100 per biquad.
Choice of internal or external clock.
No external components other than clock or crystal.
