Hall-effect sensors are typically lower cost and robust for simple position sensing. AMR (Anisotropic Magnetoresistive) sensors offer much higher sensitivity and are preferred for precise angle and compass measurements.
Linear Magnetic Sensors & Compass ICs Component Intelligence
Precision magnetic field sensing for position, orientation, and current monitoring.
What are Linear Magnetic Sensors & Compass ICs components?
Linear magnetic sensors and compass ICs convert magnetic flux density into proportional electrical signals. Choose based on sensing technology (Hall, AMR, GMR), required sensitivity, bandwidth, and package type to ensure accurate position or orientation feedback.
How to Choose Linear Magnetic Sensors & Compass ICs Components
Selecting the right magnetic sensor requires balancing sensitivity, noise floor, and environmental robustness.
Technology Selection
Choose Hall-effect for cost-effective general position sensing; use AMR or GMR for high-sensitivity, high-accuracy angle and compass applications.
Sensitivity & Range
Match the sensor's linear range to your expected magnetic field strength to avoid saturation and maintain signal linearity.
Bandwidth Requirements
High-speed current sensing requires high-bandwidth sensors, whereas static position sensing can prioritize lower noise and power consumption.
Package & Integration
Consider surface-mount vs. through-hole packages based on your PCB assembly process and mechanical mounting constraints.
Thermal Stability
Check the temperature coefficient of sensitivity to ensure accuracy remains within limits across your device's operating temperature range.
