LM1815N

Sensor And Detector Interfaces Overview

The LM1815N is an adaptive variable reluctance sensor amplifier manufactured by Texas Instruments. It is housed in a 14-pin plastic dual in-line package (PDIP-14). The device operates within a temperature range of -40°C to 125°C and draws a maximum supply current of 6 mA. It features logic inputs and logic outputs, designed for interfacing with variable reluctance sensors. The component is RoHS compliant and classified under EAR99.

Sensor And Detector Interfaces Feature Summary

• Adaptive sensing capability for variable reluctance sensors
• Logic-level input and output compatibility
• Industrial temperature range operation

Sensor And Detector Interfaces Applications

• Variable reluctance sensor signal conditioning
• Automotive speed sensing systems
• Industrial position detection interfaces

Sensor And Detector Interfaces Procurement Notes

Verify the specific ordering suffix and package type against the manufacturer's latest datasheet before procurement. Confirm that the PDIP-14 package matches the target PCB footprint requirements. Ensure compliance with RoHS directives if required by the end application standards. Check for any recent product change notifications regarding manufacturing location or material composition updates.

Sensor And Detector Interfaces Selection Notes

Select this component when an adaptive amplifier for variable reluctance sensors is required in a through-hole DIP package. Consider the LM1815MX/NOPB variant if surface mount technology is preferred for the assembly process. Verify that the 6 mA supply current fits within the system power budget constraints.

Sensor And Detector Interfaces Part Context

The LM1815 series includes variants such as the LM1815M and LM1815MX/NOPB. The LM1815M has been discontinued, with the LM1815MX/NOPB serving as the recommended replacement. The LM1815N represents the traditional through-hole packaging option within this family of sensor interface integrated circuits.

Sensor And Detector Interfaces Replacement Considerations

The LM1815MX/NOPB is the manufacturer-recommended replacement for the discontinued LM1815M. Note that the MX variant uses a 14-SOIC surface-mount package, requiring layout adjustments compared to the PDIP-14 LM1815N.
