This KWIK (Know-how With Integrated Knowledge) Circuit FAQ is a step-by-step guide that goes through the key considerations when designing an anti-aliasing architecture using Sallen-Key filters. The circuit highlighted in the FAQ consists of the LTC2066 to realize the Sallen-Key, two pole, low pass filter, in unity gain. The note goes through how to achieve this for a given set of application circuit requirements, it illustrates how these are addressed using generic formulae and makes them easily scalable to other similar application specifications. |
