LM1815N/NOPB

Sensor And Detector Interfaces Overview

The LM1815N/NOPB is a specialty analog integrated circuit manufactured by National Semiconductor, now part of Texas Instruments. It is housed in a 14-pin Plastic Dual In-Line Package (PDIP-14). The device operates within an extended temperature range from -40°C to +125°C and complies with RoHS standards. It functions as an adaptive variable sensor interface IC with logic inputs and outputs. The maximum supply current is specified at 6 mA. The component exhibits a moisture sensitivity level of 1 and carries an ECCN classification of EAR99.

Sensor And Detector Interfaces Feature Summary

• Adaptive variable sensor interface capability
• Logic input and output compatibility
• Extended industrial temperature operation

Sensor And Detector Interfaces Applications

• Sensor interface circuits
• Variable sensor signal conditioning
• Industrial control systems

Sensor And Detector Interfaces Procurement Notes

Verify the manufacturer designation as National Semiconductor or Texas Instruments on official datasheets. Confirm the PDIP-14 package type and the NOPB lead-free suffix. Ensure the operating temperature range matches the required -40°C to +125°C specification for the target application environment.

Sensor And Detector Interfaces Selection Notes

Select this component when a dedicated analog circuit for adaptive variable sensors is required. The PDIP-14 through-hole package suits prototyping or applications requiring manual assembly. Verify that the 6 mA supply current fits the power budget constraints of the system design.

Sensor And Detector Interfaces Part Context

This part belongs to the LM1815 family of specialty analog circuits. The N suffix indicates the PDIP-14 plastic dual in-line package variant. The NOPB suffix denotes a lead-free and rohs-compliant version of the original National Semiconductor product line.

Sensor And Detector Interfaces Replacement Considerations

The LM1815MX/NOPB serves as a surface-mount alternative using a 14-SOIC package. Both variants share the same core functionality and electrical specifications. Pinout compatibility differs due to the package change.
