Product Description
The CT100 is a 1D linear sensor in full-bridge configuration
from Crocus Technology developed on its patented
XtremeSense® TMR technology. The total magnetic field
range for the CT100 is from -50 mT to +50 mT and it
achieves a linearity error of ±0.5% for a range of -20 mT to
+20 mT while providing XtremeSense® per
formance to
achieve unparalleled temperature stability across the full
temperature range. It supports a wide operating voltage
range of 1.0 V to 5.5 V.
It is available in a 6-lead SOT23 package and for space
critical applications, a low profile and small form factor 6-
lead DFN package that is 1.50 × 1.50 × 0.45 mm in size.
The CT100 is also made available in die form where it will
be shipped as unsawn wafers (wafer map files
will be
provided to indicate known good die).
