Analog voltage output for 360° angle sensing
The TLE4998P3C is a programmable linear Hall sensor from Infineon that outputs an analog voltage proportional to the angle of an external magnetic field. It delivers both cosine and sine signals, which a host microcontroller can decode via arctangent to resolve absolute angle over a full 360° electrical range with continuous mechanical rotation. Operating from a single 3.3 V supply and rated from -40°C to 125°C, this sensor is suited for automotive and industrial angle-measurement applications such as steering-angle sensors, throttle position, or motor-commutation feedback where the magnetic target rotates continuously.
Supply rail and temperature grade
The 3.3 V supply rail is common in modern mixed-signal designs, but the sensor's analog output swing will be ratiometric to that rail — budget the ADC reference accordingly. The -40°C to 125°C operating range covers under-hood automotive and outdoor industrial enclosures without active cooling. Because the output is analog voltage rather than a digital bus, the signal chain needs an ADC with sufficient resolution to capture the sine/cosine pair. The continuous 360° mechanical rotation means there is no end-stop; the sensor tracks through multiple turns if the external magnet rotates freely.
