LM1815
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 negativegoing zero crossing of a ground referenced input signal such as from a variable reluctance magnetic pick-up coil.
Key Features
- 2 Adaptive Hysteresis

- Ground Referenced Input
- True Zero Crossing Timing Reference
- Operates from 2V to 12V Supply Voltage
- Handles Inputs from 100 mVP-P to over 120VP-P with External Resistor
- CMOS compatible Logic
