Dot/Bar Display Driver - LM3914N
One of the best analog ICs ever made - the LM3914N Dot/Bar display driver. These ICs are no longer in production, but we still have limited stock. Use these for VU meters or other 10-step bar graphs. These can also be cascaded to create bar graphs of 40 or even 50 LEDs.
These are used in our 40-step LED Bar Graph kit.
