1 Electrical Specifications
The SCA100T product family comprises two versions, the SCA100T-D01 and the SCA100T-D02
that differ in measurement range. The product version specific performance specifications are
listed in the table SCA100T performance characteristics below. All other specifications are
common with both versions. Vdd=5.00V and ambient temperature unless otherwise specified.

Note 1. The frequency response is determined by the sensing element’s internal gas damping.
Note 2. The angle output has SIN curve relationship to voltage output refer to paragraph Error! Reference source not
found.
Note 3. Resolution = Noise density * √(bandwidth)
Note 4. Power continuously connected (@ 23°C).
