Product Description
Product Description
The CT310 is a 2D angular sensor utilizing Crocus Technology's patented XtremeSense 2D TMR technology, built on a dual full-bridge configuration. It offers an angular error of less than 0.30 after compensation across the full operating temperature range. The sensor operates within a magnetic field range of 25 mT to 90 mT and provides differential outputs for both sine (SIN) and cosine (COS) axes. It supports a supply voltage range from 1.0 V to 5.5 V and is available in an 8-lead TSSOP package or a compact 8-lead DFN package (2.00 x 2.00 x 0.45 mm) for space-constrained applications.
