THIS DOCUMENT IS FOR MAINTENANCE PURPOSES ONLY AND IS NOT RECOMMENDED FOR NEW DESIGNS DS 3301 -1 SL6270C GAIN CONTROLLED MICROPHONE PREAMPLIFIER/VOGAD 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.

The dynamic range, attack and decay times are controlled by exte
