The LM3914 is a legendary analog integrated circuit. Designed by National Semiconductor (now Texas Instruments), this monolithic dot/bar display driver has been the go-to solution for visualizing analog voltage levels for decades. Whether you’re building a battery monitor, a VU meter, a temperature indicator, or a simple signal strength meter, the LM3914 simplifies driving ten LEDs in a logarithmic or linear fashion. lm3914 ltspice model

When using a downloaded , you will likely encounter these issues:

For simulation, use ideal comparators with mode control : The underlying SPICE code that defines the

As of 2025, the most reliable pre-built model is available from:

The is a popular monolithic integrated circuit designed to sense analog voltage levels and drive a 10-segment LED bar graph. Because it is not natively included in the LTspice library, users must typically source or create a subcircuit ( .sub ) and symbol ( .sym ) file to simulate its behavior. Core Functionality for Simulation Whether you’re building a battery monitor, a VU

For simplicity, we use voltage-controlled switches.
