Hall Device
LT120A
¡ Small temperature coefficient of the Hall voltage
¡ Good linearity of the Hall voltage
¡ Small imbalanced voltage
¡ Directly DC voltage applicable
¡ Brushless motors
¡ Measuring equipment
¡ Noncontact sensors
¡ Other magnetic detection
*1 Soldering time : 10 seconds
*1 No-load Hall voltage is nearly proportional to Vc (within the range of 1 to 6V) at temperatures of -20˚C to + 125˚C.
*2 Imbalanced ratio is in +/-12% within the range of Vc=1 to 6V.
