The TMR3026 angle sensor IC is designed with two sets of redundant Wheatstone bridge structures. Each Wheatstone bridge consists of four high-sensitivity tunneling magnetoresistance (TMR) sensing elements, forming two half-bridge structures that output single-ended SIN and COS voltages respectively. The TMR Wheatstone bridge structure effectively compensates for sensor thermal drift.

In angle sensor applications, a magnet is placed above the TMR3026 angle sensor IC to provide an operating magnetic field parallel to the chip surface. When the magnet rotates, the IC outputs voltage signals with sine and cosine relationships to the magnetic field angle.

The redundant design of the TMR3026 improves application system safety. It maintains very low angle error when the magnetic field varies within the range of 200 Gs to 800 Gs. The IC is available in an SOP8 package.
