ALT521-10E Rotational Sensors are Tunneling Magnetoresistance (TMR) Wheatstone bridge sensors with large voltage signal, wide linear range, and ultraminiature package size. The sensor has two half-bridge outputs for absolute angle detection or both X- and Y-axis magnetic field detection. The outputs are bipolar, meaning they are positive for a positive field and negative for a negative magnetic field polarity.
Key specifications are:
• High sensitivity (140 mV/V/mT)
• ±0.5 mT linear range
• Highly linear output (typ. 2% of full scale)
• Low temperature coefficient of output (0.1%/°C)
• 100 kHz frequency bandwidth
• 2 megohm typ. device resistance for low power
• Operation to near-zero supply voltage
• Up to 125 °C operating temperature
• 2.5 x 2.5 mm DFN6 package
