AHG-0A11
Specifications: The AHG-0A11 represents the extreme miniaturization of GaAs Hall technology in a tiny DFN package (0.8x0.4x0.21mm). It operates at 10mA input, providing a standard 36-54mV Hall output with balanced 650-850Ω resistances and ±5mV offset. Despite its microscopic size, it is fully rated for the industrial temperature range of -40°C to 125°C.
Application Scenarios: Engineered for space-constrained, high-volume applications. Perfect for integration into ultra-thin consumer electronics (smartphones, tablets, wearables) for flip cover detection, auto-rotate, and hallpixel functions. Also ideal for medical implants, micro-drones, and advanced MEMS systems where PCB real estate is at an absolute premium and automated surface-mount assembly (via Tape & Reel) is required.
AHG-106C
Specifications: The AHG-106C is a surface-mount GaAs Hall element in a robust SSOP-4 package. It features standard performance parameters: 13mA input, 36-54mV Hall voltage, balanced 650-850Ω resistances, and ±5mV offset. It is built for reliability across the industrial temperature range of -40°C to 125°C.
Application Scenarios: This component offers a good balance of size, solderability, and ruggedness. It is widely used in automotive body electronics (door ajar switches, seat belt sensors), industrial automation (position limit switches, valve state detection), and appliance control boards. The SSOP-4 package provides better thermal and mechanical performance than DFN for harsh environments, while still allowing automated assembly.
AHG-116C
Specifications: The AHG-116C is a SSOP-4 packaged GaAs Hall element with specifications identical to the AHG-106C: 13mA input, 36-54mV output, 650-850Ω resistances, ±5mV offset, and a -40°C to 125°C operating range.
Application Scenarios: Serving as a direct alternative to the AHG-106C, it is used in similar automotive, industrial, and appliance applications. It is particularly suitable for multi-sensor designs requiring redundancy or for manufacturers seeking a second source for a standard surface-mount Hall element, ensuring supply chain flexibility without redesigning the PCB or control circuitry.
AHG-302C
Specifications: The AHG-302C is a standard through-hole GaAs (Gallium Arsenide) Hall element in a SIP package. Key electrical parameters include a maximum input current of 13mA, a Hall voltage range of 36-54mV under a standard magnetic field, and symmetrical input/output resistances of 650-850Ω. It features a low offset voltage of ±5mV and is designed for harsh environments with an operating temperature range of -40°C to 125°C.
Application Scenarios: This element is a reliable, cost-effective choice for general-purpose magnetic sensing. It is ideal for building custom magnetic switches, position sensors (e.g., in appliance lids or valves), and low-resolution rotary encoders. Its through-hole SIP package makes it suitable for prototyping, educational kits, and industrial equipment where manual assembly and robust, long-term reliability in variable temperatures are valued over miniaturization.
ASH-72D
Specifications: The ASH-72D is a miniature GaAs Hall element, functionally identical to the AHG-0A11, housed in the same ultra-small DFN package. It shares the 10mA input, 36-54mV Hall voltage, 650-850Ω resistances, ±5mV offset, and -40°C to 125°C temperature rating.
Application Scenarios: As a pin-compatible alternative to AHG-0A11, it targets the same high-density, portable electronics market. It is used in compact modules for IoT devices, in-card sensors for smart cards and security tokens, and as a non-contact switch in hearing aids or other micro-medical devices, offering reliable magnetic sensing in the smallest possible form factor for automated manufacturing.
ATHS119
Specifications: The ATHS119 is a GaAs Hall element sharing identical specifications with the AHG-302C, housed in the same SIP package. It is characterized by a 13mA max input, a Hall voltage of 36-54mV, balanced input/output resistance (650-850Ω), and a ±5mV offset voltage. It is rated for the full industrial temperature range from -40°C to 125°C.
Application Scenarios: Functionally equivalent to the AHG-302C, it serves as an alternative source or drop-in replacement for the same applications. It is commonly used in brushless DC (BLDC) motor commutation circuits for low-cost fans, in proximity detection modules, and as the sensing core in legacy or cost-sensitive industrial control systems requiring a discrete, analog Hall sensor with predictable performance.
