What this part is and where it fits
The MAX9926UAEE+T from Analog Devices is a dedicated sensor interface IC designed to condition variable-reluctance (VR) and differential sensor signals into a clean logic-level output. It takes a differential input from a magnetic pickup or VR sensor and outputs a logic pulse train that an ECU or controller can read directly. This part is built for automotive and industrial environments where engine speed, cam/crank position, or rotational speed must be captured reliably over a -40°C to 125°C temperature span. The 10 mA supply current keeps the thermal budget manageable in a sealed ECU or transmission controller.
What the ratings mean for the BOM
The 10 mA supply current is the total draw for the IC. The -40°C to 125°C range covers under-hood automotive and industrial engine-bay environments.
