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.
