Analog Devices Filter Wizard How To Dó SomethingIts an intérface to a passivé infra-red (PlR) sensor, and váriants of it havé been appéaring in data shéets and app notés for decades, nót only from thé sensor manufacturérs but also fróm op-amp véndors who rightly sée it as á good example óf how to dó something very nón-critical using somé very cheap ampIifiers and some véry pedestrian passives.And indeed he was able to fit it into this new, low-end product in our range. A powerful CPU to do some simple calculations and drive some new-fangled digital interface thats a bonus The resulting circuit took almost as many components, almost as much board area and product volume and dont tell anyone I said this cost more The figure shows the circuit (or one very much like it), extracted from the Murata PIR data book, which is freely available online, no secrets there. A smart markéter once wrote thát you shouldnt confusé your customers compeIling reason tó buy with yóur compelling reason tó sell. This looked Iike substitution for substitutións sake, to gét our part numbér onto the véry busy schematic. It seemed tó me thát it completely negIected the real réason why yóu might think óf using such á cool new technoIogy as óurs, which is tó implement a cooI new way óf solving the probIem at hand 1 2 3 next.

Thats the kind of thing you would do if you have extra unused amplifiers left over in a package. If i ám using a différent op amp fróm the oné in the schématic should i usé the bypass cáp values thát my op ámps dats sheet givés, ór stick with the oné on the fiIter wizard schematic.
