LM1815 Adaptive Variable Reluctance Sensor Amplifier

The LM1815 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 negativegoing zero crossing of a ground referenced input signal such as from a variable reluctance magnetic .
