Electrical Specifications
The SCA61T product family comprises two versions, the SCA61T-FAHH1G and the SCA61T-
FA1H1G, that differ in measurement range. The product version specific performance
specifications are listed in the following table below. All other specifications are common to 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 2.2
Note 3. Resolution = Noise density * √(bandwidth)
Note 4. Power continuously connected (@ 23°C).
