BOM rule hits · not reviewed — A hit means a BOM line matched this category's rules (ruleset 1.0.1+12960cbec977). It is a lead to read, not a located or reviewed circuit; several lines in one category are not several circuits.
Selection parameter template (suggestion)
What one usually states when choosing a circuit of this kind — not the parameters of any design or module listed here, and never a filter.
| Parameter | Suggested range or common values | Where it comes from |
|---|---|---|
| TypeDecisive | MEMS digital (I2S/PDM)MEMS analogElectret | This category's own |
| Sensitivity (dBFS)Important | -46 to -26 dBFS | This category's own |
| Signal-to-noise ratio (dB)Important | 58 to 75 dB | Redefined here |
In the parent's template, not in this one: Channels, Sample rate / bit depth, Digital interface, THD+N
