Description
TMR2185 TMR linear sensor adopts a unique push-pull Wheatstone full bridge structure utilizing four TMR sensor elements. This Wheatstone full bridge provides differential voltage output with excellent temperature stability when the applied magnetic field changes parallel to the sensor’s sensitive direction. The TMR2185 linear magnetic sensor is available in SOP8 and LGA4L (2 mm × 1.5 mm × 0.73 mm) package with P/N of TMR2185P and TMR2185G. Features and Benefits
- Tunneling magnetoresistance (TMR) technology
