LM1815 Datasheet Adaptive Variable Reluctance Sensor Amplifier

Manufacturer: National Semiconductor (now Texas Instruments)

General Description

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 negative-going zero crossing of a ground referenced input signal such as from a variable reluctance magnetic pick-up coil.

In normal operation, this timing reference signal is processed (delayed) externally and returned to the LM1815.
