Packaging

The CT310 is a 2D angular sensor in a dual full-bridge configuration from Allegro MicroSystems developed on its patented XtremeSense™ TMR technology. The operating magnetic field for this 2D sensor is 20 mT to 90 mT and has an angular error as low as 0.6° after compensation over the full operating temperature range. The CT310 has excellent performance which helps it to achieve excellent stability over the full temperature range. It has differential outputs for both sine (SIN) and cosine (COS) axes and operates with a supply voltage range from 1.0 V to 5.5 V.

  • Contactless Angle Measurement from 0° to 360°
  • Angular Error less than 0.30° (After Compensation)
  • Dual Full-Bridge Resistor Network
  • Operating Magnetic Field: 25 mT to 90 mT
  • Stable Magnetic Performance Over Temperature
  • Differential Outputs for SIN and COS Axes
  • Wide Operating Temperature Range
    • Industrial: -40°C to +85°C
    • Extended Industrial: -40°C to +125°C
    • Full: -40°C to +150°C
  • Package Options:
    • 8-lead TSSOP
    • 8-lead DFN, 2.00 x 2.00 x 0.45 mm
    • KGD (Known Good Die) in Wafer Form

It is packaged in an 8-lead TSSOP package and for applications where space is critical, a low profile, small form factor 8-lead DFN package that is 2.00 x 2.00 x 0.45 mm in size. The CT310 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).
