Product Specification
| Voltage - Supply | 1.8V~12V | Description | SOP-16 Linear, Compass (ICs) RoHS |
| Mfr. Part # | AMR2302 | Package | SOP-16 |
| Model Number | AMR2302 |
The AMR2302 is a high-accuracy, low-noise dual-axis linear magnetic sensor utilizing Anisotropic Magnetoresistance (AMR) technology. It employs two push-pull Wheatstone bridges for effective temperature drift compensation and minimal noise, offering excellent temperature stability. Available in a SOP16 package, it is suitable for weak magnetic field sensing, current sensing, position sensing, and magnetometer applications.
