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).
