Behavior of the analog output

The analog output can be transferred to angle by using the following equation for conversion:

where Offset is the output of the device at 0° inclination position, Sensitivity is the sensitivity of the

device and VDout is the output of differential amplifier.

In the case of differential amplifier connection shown in the chapter Recommended circuit diagram

the nominal offset output is 0 V and the sensitivity is 16 V/g with SCA103T-D04 and 8 V/g with

SCA103T-D05.
