ALT021-10E Evaluation Board With Amplifier ALT021-10E: 0-0.25 mT TMR Bipolar Analog Sensor, 20 KOhm, DFN6 Part Number ALT021-10E Technology TMR Magnetic Polarity Bipolar Field Measurement Range (mT) -0.25 to +0.25 Current Measurement Range (A) 0.1 to 10 Sensitivity (mV/V/mT) 500 Output Bridge Min. Detectable Field (µT) 0.1 Direction of Sensitivity Cross-axis Supply Voltage (V) 0 to 10 Bridge Resistance (kΩ) 20 Current Sensing Mode Over-trace Max. Temperature (°C) 125 Package 2.5 x 2.5 mm DFN6 Data Sheet (.pdf) Package Outline (.pdf) STEP File (.step) KiCAD Footprints (External Link) × × Model for 2.5-x-2.5-mm-DFN6 Description: The ALT021 is an ultrahigh sensitivity Tunneling Magnetoresistance (TMR) analog bridge magnetic sensor. The differential bridge output is bipolar, meaning it is positive for a positive field and negative for an opposite field polarity. Features:

±0.25 mT linear range Ultrahigh sensitivity (500 mV/V/mT typical) Large output signal (200 mV/V typical) 0 - 10 V power supply Wheatstone bridge magnetometer configuration 20 kiloohm device resistance for low power Up to 300 kHz frequency bandwidth 2.5 x 2.5 mm DFN6 package –40 to 125°C Applications:
