Active production, automotive-qualified VR sensor interface
The MAX9924UAUB/V+T is an active-production sensor interface IC from Analog Devices, designed to condition variable-reluctance (VR) magnetic pickup signals into a clean logic-level output for engine-speed and position sensing in automotive power-trains. Its differential input architecture rejects common-mode noise on the long twisted-pair runs typical of crank- and camshaft sensors, while the logic output drives directly into an ECU's digital input or timer-capture pin.
Automotive temperature range and AEC-Q100 qualification
AEC-Q100 qualification means the IC has passed the full suite of automotive stress tests: high-temperature operating life, ESD, latch-up, and temperature cycling. That certification is a prerequisite for tier-1 PPAP submissions.
Package, supply, and compliance
Housed in a 10-pin TFSOP/MSOP (3.00 mm width) — the 10-uMAX/uSOP footprint — the part suits space-constrained ECU boards where every mm² counts. Draws 5 mA from the supply rail, a modest budget for a sensor interface that stays powered continuously in a running engine. ROHS3 compliant, with no exemption conflicts for automotive builds bound for EU markets.
