Sensor interface with differential front end
The MAX9925AUB+ is a sensor interface IC from Analog Devices, designed to condition differential sensor signals into a logic-level output. The differential input architecture rejects common-mode noise picked up on long sensor leads, making it suited for variable-reluctance or magnetic pickups in engine management, transmission control, and industrial speed-sensing applications where the signal source is remote from the processing electronics.
Package and board-fit details
The supplier device package is designated 10-uMAX/uSOP. The logic output interfaces directly with a microcontroller or DSP input pin without external level translation, provided the supply voltage of the receiving device matches the interface IC's output swing.
