It draws 1.3 mA from the supply, low enough to keep the sensor alive in battery-backed or always-on subsystems without eating into the power budget. The operating temperature range of -40°C to 125°C covers automotive under-hood, industrial motor compartments, and outdoor telecom enclosures where the ambient can swing hard. ## Package and mounting — fits a tight PCB footprint Housed in a 10-MSOP package (3.00 mm body width) and specified for surface-mount assembly, the MAX9921AUB+ suits dense PCB layouts where board area is at a premium. The supplier device package is listed as 10-uMAX/uSOP — same footprint, different supplier code. Verify the land pattern against your assembly house's stencil aperture for the 0.118-inch body width; no surprises if you have placed other 10-MSOP Hall sensors before. ## Lifecycle and compliance — no LTB watch needed Marked as Active in the lifecycle record, so there is no last-time-buy clock running on this part. ROHS3 compliant, which clears the EU material restrictions for new designs.","metaTitle":"MAX9921AUB+ Hall Effect Sensor, 1.3 mA, -40°C to 125°C","metaDescription":"MAX9921AUB+ Hall Effect Sensor from Analog Devices.
