LM3916N-1/NOPB

Display Drivers Overview

The LM3916N-1/NOPB is a dot/bar display driver IC manufactured by Texas Instruments. It features a logarithmic scale output suitable for LED level indication. The device operates on a single supply voltage ranging from 3 V to 20 V. It includes an internal voltage reference and programmable output current capabilities. The component is housed in a PLCC-20 package with surface mount installation. It supports up to 10 output channels and functions within a temperature range of 0°C to +70°C.

Display Drivers Feature Summary

• Provides logarithmic scaling for accurate audio or signal level visualization
• Integrates an internal voltage reference for stable operation without external components
• Features programmable output current control for flexible LED drive configurations

Display Drivers Applications

• Audio equipment level meters
• Signal strength indicators
• Battery status displays

Display Drivers Procurement Notes

Verify the specific suffix N-1 against the datasheet to confirm logarithmic functionality, as standard variants may differ. Ensure the PLCC-20 footprint matches the PCB layout. Confirm RoHS compliance status via the manufacturer's official documentation before finalizing procurement specifications.

Display Drivers Selection Notes

Select this component when a logarithmic response curve is required for visual level indication. Compare against linear variants like the LM3914 if the application demands equal voltage steps per LED. Verify that the 20 V maximum supply voltage aligns with the system power rails.

Display Drivers Part Context

This part belongs to the LM391x family of display drivers from Texas Instruments. It serves as the logarithmic counterpart to the linear LM3914 and the quasi-linear LM3915. The NOPB suffix indicates lead-free construction compliant with environmental standards.
