Differential Multiple Feedback Chebyshev Low Pass Filter

Problem:
How does a designer make a Differential Multiple Feedback Chebyshev low pass filter?

Solution:
Use the circuit below:



This circuit has a fixed gain of 1 (0 dB) and 3 dB ripple. For other gains and levels of ripple, call Texas Instruments Applications.

Differential filters are symmetrical. Passive components are mirror imaged on the top and bottom of the schematic. Components closing the top loop have an "A" suffix, and those closing the bottom loop have a "B" suffix.
