DESCRIPTION
The CT100 is a 1D linear sensor in full-bridge configuration
from Allegro 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
performance to achieve unparalleled temperature stability
across the full temperature range. The device supports a wide
operating voltage range of 1.0 to 5.5 V.
The CT100 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 mm × 1.50 mm × 0.45 mm in
size. The CT100 is also available in die form where it will be
shipped as unsawn wafers (wafer map files will be provided
to indicate known good die).
