LM3914 Logarithmic LED dot or bar display driver 18 pin IC pack of 2pcs

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) ten 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 2 pieces of LM3914 Logarithmic LED dot or bar display driver 18 pin IC

Features

  • LED driver IC controlled via analog with logarithmic output
  • LED increased by one step for each three decibels
  • Monitor up to 30dB using 10 LEDs
  • Output current is programmable from 1 mA to 30 mA
