Specifications: The AHG-166A is the surface-mount SSOP-4 version of a high-sensitivity GaAs Hall element. It operates at 14mA, delivering a high 80-110mV Hall voltage. It has an input resistance of 1.0-1.5kΩ, a higher output resistance of 1.8-3.0kΩ, and an offset of ±8mV. It is specified for -40°C to 125°C.

Application Scenarios: Its high sensitivity in a robust SMD package makes it ideal for precision applications in challenging environments. Common uses include contactless current sensors for motor drives and power supplies, joystick and control lever position sensing in industrial machinery, and high-resolution angular or linear position sensors in automotive throttle or pedal applications.
