LM1815M Adaptive Variable Reluctance Sensor Amplifier IC (SOP-14)

LM1815M Adaptive Variable Reluctance Sensor Amplifier IC (SOP-14)

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
