DESCRIPTION
The CT310 is a 2D angle sensor in a dual full-bridge configuration
from Allegro developed on its patented XtremeSense™ 2D tunnel
magnetoresistance (TMR) technology. The operating magnetic
field for this 2D sensor is 250 to 900 G and has an angle error
less than 0.60° over temperature following a one-time offset,
gain, and phase compensation. The sensitive axes of the TMR
elements are orthogonal to each other, providing a 90° phase
separation between the sine and cosine outputs when measured
differentially. This phase separation is inherently independent
of magnet pole spacing and air gap.
The CT310 is available in an 8-lead TSSOP package, and for
space-critical applications, a low-profile and small form factor
8-lead DFN package that is 2.00 mm × 2.00 mm × 0.45 mm
in size. The packages are RoHS compliant and lead (Pb) free
with a 100% matte-tin-plated leadframe.
