LM1815 Datasheet Adaptive Variable Reluctance Sensor Amplifier

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM1815 Adaptive Variable Reluctance Sensor Amplifier June 2001 LM1815 Adaptive Variable Reluctance Sensor Amplifier.

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.
