LM3914 Logarithmic LED dot or bar display driver 18 pins IC pack of 50pcs

This is an all-in-one IC. It is applied to audio signal visualization. This IC is capable of driving both Dot Matrix LEDs and 10-segment bar LEDs. Based on the analog input voltage of the audio stream, it can regulate (turn on or off) 10 LED lights. This integrated circuit has a precise ten-step voltage divider and an adjustable voltage reference. Applying the LM3914 is quite simple. The use of microcontrollers and programming is eliminated with this IC. Additionally, it requires less circuitry to control 10 LEDs.

Package includes
This is the pack of 50 pieces of LM3914 Logarithmic LED dot or bar display driver 18 pin IC

Features

  • Analog controlled LED driver IC with logarithmic output
  • For every 3dB, the LED increased by one step.
  • Monitor up to 30dB using 10 LEDs
  • Output current is programmable from 1 mA to 30 mA
