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.
