Electrical Specifications

The SCA103T product family consists of two versions, the SCA103T-D04 and the SCA103T-D05,

that differ in measurement range. The specific performance specifications related to each version

are listed in the table “SCA103T performance characteristics” below. All other specifications are

common to both versions.

The supply voltage is Vdd=5.00V and ambient temperature unless otherwise specified. Parameters

marked as D are valid when measured in differential mode using an external differential amplifier.

Parameters marked with S are for a single measurement channel. The performance of the selected

amplifier may have an effect on some parameters. The differential signal is determined as Out_diff

= Out1

– Out2.

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 chapter 2.2
