The Analog I/O Cell Configured as a Sallen-Key Filter
The AN10E40 Analog I/O cells are especially designed to accommodate the construction of Sallen-Key topology
filters. These filters are easily constructed and are handy for input anti-aliasing or output switching noise filtering. In
this particular test, the filter was designed to roll off at 200 kHz.
Many of the measurements shown below are repeated several times with different weighting factors. CCIR IEC
468-3 Weighted and A-Weighted measurements are two standard Psophometric weightings common to audio and
communications equipment manufacture.
