LM1815M TI Adaptive Variable Reluctance Sensor Interface | 14-SOIC | 2.5V to 24V, 1.5mA

Product Overview

The LM1815M from Texas Instruments is a complete adaptive variable reluctance sensor interface designed for automotive and industrial applications. It processes signals from variable reluctance magnetic pickups, converting them into a clean digital output. The device operates over a wide supply voltage range of 2.5V to 24V and features adaptive threshold control, ensuring reliable operation across varying signal amplitudes and speeds. Housed in a compact 14-SOIC package, the LM1815M is ideal for space-constrained designs.
