Honeywell SS490 Series Linear Sensor ICs
Honeywell SS490 Series Linear Sensor ICs are Hall-effect devices that detect magnetic fields from permanent magnets or electromagnets. The SS490 linear sensor ICs feature high accuracy and temperature compensation from laser-trimmed resistors, allowing them to respond to both positive and negative Gauss. These ICs support a temperature coefficient of +0.02%/°C and operate within a temperature range from -40°C to +150°C. SS490 ICs offer rail-to-rail operation for higher accuracy signals and come in various package styles for design flexibility. Typical applications include anti-tampering magnetic field sensors, basic current sensing for motor load monitoring and detection, current sensing in appliances, and simple linear or angular displacement sensing.
