The LM1815N/NOPB from Texas Instruments is an adaptive sense amplifier and default gating circuit suitable for motor control applications. This component provides a one-shot pulse output synchronized with the negative-going zero crossing of a ground-referenced input signal, such as from a variable reluctance magnetic pick-up coil.
Key electrical characteristics include a supply voltage range of 2V to 12V and an operating temperature range of -40°C to 125°C. It handles input signals from 100 mV P-P up to over 120V P-P with an external resistor. The device features adaptive hysteresis, single supply operation, a ground-referenced input, and true zero crossing timing reference.
Packaged in a 14-PDIP or 14-DIP format, the LM1815N/NOPB is designed for through-hole mounting. Its logic output and CMOS compatible logic make it versatile for various interface designs. The adaptive sense amplifier's threshold varies with input signal amplitude, enabling sensing in noisy environments.
This sensor interface IC is a valuable component for applications requiring precise signal conditioning and zero-crossing detection from variable reluctance sensors.
