The LM1815M is an adaptive variable reluctance (VR) sensor amplifier designed for detecting and conditioning signals from magnetic pickup sensors, such as those used for engine speed, crankshaft, and wheel speed sensing. It provides a clean digital output compatible with microcontrollers and logic circuits, making it ideal for automotive and industrial applications.
Features:
Adaptive peak detection for variable signal amplitudes
Operates with variable reluctance (magnetic pickup) sensors
Digital output for easy interface with logic circuits
Wide operating voltage range: 4.75V — 28V
Internal hysteresis for improved noise immunity
Compact SOP-14 surface-mount package
Applications:
Engine speed or position sensing
Crankshaft or camshaft sensors
ABS wheel speed detection
Industrial proximity or motion detection
Package Type: SOP-14
