Its ±40 mT sensing range covers linear position, proximity, and current-sense applications where the magnetic flux stays within that window — beyond it the output saturates, so the mechanical air gap and magnet strength must be set to keep the field inside the linear band. The analog output simplifies the signal chain: a single ADC channel reads the voltage, and the system firmware maps it to gauss or position. No digital interface overhead, but the ADC's reference accuracy and noise floor set the usable resolution — the sensor itself is 8-bit, so a 10-bit or higher ADC captures the full scale without quantization loss. ## Supply range and power budget Maximum supply current is 1.5 mA, and with Sleep Mode available, the average draw in a duty-cycled system drops well below that — the sleep current isn't specified here, but the feature is intended for battery-powered designs where the sensor wakes, takes a reading, and goes back to sleep. If the ADC input impedance is below 10 kΩ, a unity-gain buffer between the sensor and the converter keeps the reading accurate. ## Package and thermal interface Housed in a 6-UDFN exposed-pad package (U-DFN2020-6 Type C), the sensor measures 2.0 mm × 2.0 mm with a 0.65 mm typical seated height. The exposed pad on the bottom side must be soldered to a PCB copper land and connected to ground — this provides the thermal path for self-heating and also stabilises the magnetic offset by tying the substrate to a quiet reference plane. Surface-mount assembly with a standard lead-free reflow profile; the package is compatible with JEDEC MSL-1 (moisture sensitivity level is not explicitly stated, but the exposed-pad construction typically requires bake before reflow if the bag humidity indicator card shows >10 % RH). Tape-and-reel packaging supports automated pick-and-place for volume production. ## Temperature grade and industrial fit The Hall element itself has no wear mechanism, so the lifetime is limited by the package solder joints and the PCB's thermal cycling endurance.","metaTitle":"AH8501-FDC-7 Diodes Hall Sensor, ±40 mT, 6-UDFN","metaDescription":"AH8501-FDC-7 Hall effect sensor, single-axis, analog output, ±40 mT range, 1.6-3.6 V supply, -40 to 85°C, 6-UDFN.
