• Hall voltage: typ. 105 mV (VC = 6 V, B = 0.1 T)
• Input resistance: typ. 0.75 kΩ
• Satisfactory linearity of GaAs hall voltage with respect to the
magnetic field
• Small temperature coefficient of the hall voltage: β ≤ − 0.06%/°C
• Sealed in the Mini type (4-pin) package. Allowing automatic
insertion through the taping and the magazine package.

Output pin voltage under no-load (B = 0) condition
The linearity γ of VH is a percentage of a difference between cumulative sensitivity of KH1 and KH5 which are measured
respectively at B = 0.1 T and 0.5 T to their average. That is,
