http://www.daycounter.com/Filters/Sallen-Key-HP-Calculator.phtml WebOct 6, 2004 · Sallen-Key filters have the filter type determined by many things including gain. LR filters are simple an even number of Butterworth filter cascaded togther. therefore, there cannot be LR3 or LR5 filters, only LR2, LR4, LR6, etc. and, any even number of Butterworth filter should be a LR, not just a Butterworth.

Vref provides a DC offset to accommodate for single-supply applications. A Sallen-Key filter is usually preferred when small Q factor is desired, noise rejection is prioritized, and when a non-inverting gain of the filter stage is required.
