Footnotes:
1. Characteristics are subject to change. Values assume supply voltage of 3 VDC.
2. Measurement taken with no sensor activity
3. Measurement taken during continuous polling of sensors
4. Field measurement range is defined a the monotonic region of the output characteristic curve
5. Gain is defined as the change in the number of counts from the ASIC when the period select is set
to 2048, per change in the magnetic field in µT. For situations requiring higher gain and less field
measurement range, the gain and resolution can be increased by a factor of 2 by setting the ASIC
period select to 4096. When setting higher selects, be aware that the ASIC counter can overflow if
the field is strong enough to drive the count beyond a signed 16-bit integer. Period select set to 2048
is the highest setting where it is impossible to overflow the counter.
6. Resolution is 1/gain to the noise limit.
7. Requires that a field calibration be performed. In practical compass applications, a calibration is
normally performed when the compass module is in the host system.
