LM1815MX/E7001793

Sensor And Detector Interfaces Overview

The LM1815MX/E7001793 is an adaptive variable reluctance sensor amplifier manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2V to 12V with a typical supply current of 6 mA. The device features adaptive hysteresis and handles input signals from 100 mVP-P to over 120VP-P using an external resistor. It provides CMOS-compatible logic outputs and includes a true zero-crossing timing reference. The component is housed in a 14-lead SOIC package and supports an operating temperature range of -40°C to +125°C.

Sensor And Detector Interfaces Feature Summary

• Adaptive hysteresis that varies with input signal amplitude to handle high-speed noise
• Ground-referenced input triggering on the negative-going zero crossing
• Logic input selection for processed or direct timing reference transmission

Sensor And Detector Interfaces Applications

• Position sensing with notched wheels
• Motor speed control systems
• Tachometer applications
• Engine testing equipment

Sensor And Detector Interfaces Procurement Notes

Verify the specific E7001793 suffix against official documentation, as standard datasheets typically list LM1815MX/NOPB. Confirm the active production status and lead times directly with Texas Instruments or authorized distributors. Ensure the ordering information matches the required 14-SOIC package and temperature specifications for your design.

Sensor And Detector Interfaces Selection Notes

Select this component for motor control applications requiring adaptive sensing of variable reluctance sensors. Ensure the input signal amplitude falls within the specified arming thresholds for the chosen mode (Pin 5 configuration). Verify that the external RC network at Pin 14 meets the frequency requirements for the one-shot pulse width.

Sensor And Detector Interfaces Part Context

This part belongs to the LM1815 family of adaptive sense amplifiers designed for robust signal processing in noisy environments. It serves as a default gating circuit for motor control, providing reliable timing references derived from magnetic pickup coils.
