LM3915 Logarithmic LED dot or bar display driver 18 pin IC pack of 2pcs

An example of a monolithic IC. It is utilised for audio signal visualisation. This IC is capable of driving both dot matrix and 10-segment bar LEDs. It is capable of activating or deactivating ten LEDs in response to an analogue input voltage of the audio signal. An adjustable voltage reference and a precise ten-step voltage divider are integrated into this IC. The LM3915 requires no special effort to utilise. Programming and the use of microcontrollers are rendered unnecessary by this IC. Additionally, the circuitry needed to control ten LEDs is reduced.

Package includes
This is the pack of 2 pieces of LM3915 Logarithmic LED dot or bar display driver 18 pin IC

Features

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