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.
