Plessey SL6270 – VOGAD

Normally this IC comes as a “8 Pin DIL version”, but some were created in “SMD” and that is what we offer here. The “SL6270″ is a silicon integrated circuit combining the functions of audio amplifier and voice operated gain adjusting device (VOGAD).

It is designed to accept signals from a low sensitivity microphone and to provide an essentially constant output signal for a 50dB range of input.


  • Constant Output Signal
  • Fast Attack Time
  • Low Power Consumption
  • Simple Circuitry
  • Supply Voltage: 4.5V to 10V
  • Voltage Gain: 52dB
  • Ambient temperature: -30°C to +85°C

Please Note: – This “SMD” version is electrically the same as the  8 Pin DIL version.
