This demonstration features the ALT025 low hysteresis, high-speed TMR magnetometer and a high current PCB layout, optimized for the detection of +/- 200 amps. The board has sturdy screw terminal connections for current input, and it has header pins for sensor power and output.
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.
