LM1815EP Datasheet (National Semiconductor) - Enhanced Plastic Adaptive Variable Reluctance Sensor Amplifier

LM1815EP, Enhanced Plastic Adaptive Variable Reluctance Sensor Amplifier

The LM1815EP is an adaptive sense amplifier and default gating circuit for motor control applications.

The sense amplifier provides a one-shot pulse output whose leading edge coincides with the negative-going zero crossing of a ground referenced input signal such as from a variable reluctance magnet
