Specifications & Instructions

SPECIFICATIONS

CAUTION:

Stresses beyond those listed under Table 2 may cause permanent damage to the device. These are

stress ratings only. Functional operation of the device at these or any other conditions beyond

those indicated in the operational sections of the specifications is not implied. Exposure to

absolute maximum rating conditions for extended periods may affect device reliability.

a. At period select 2048 and 8Hz sample rate

b. Field measurement range is defined as the monotonic region of the output characteristic curve.

c. Gain is defined as the change in the number of counts from the MS2100, when the period select is set to 2048, per

change in the magnetic field in uT. For situations requiring less gain and more field measurement range, the gain

and resolution can be decreased by a factor of 2 by setting the MS2100 period select to 1024. In practical

magnetometer applications, a sensor gain calibration is normally performed when the sensor module is in the host

system.
