GaAs Hall Device
Magnetic sensor
•
Hall voltage: typ. 105 mV (V
C
= 6 V, B = 0.1 T)
•
Input resistance: typ. 750 kΩ
•
Satisfactory linearity of GaAs hall voltage with respect to the
magnetic field
•
Small temperature coefficient of the hall voltage:
β ≤ −
0.06%/°C
•
Mini type (4-pin) package with positioning projection. Allowing
automatic insertion through the magazine package.
