TECHNICAL DATA

GAIN CONTROLLED MICROPHONE

FIER/VOGAD

PREAMPLI-

The

KK6270

is a silicon integrated circuit combining the functions of audio amplifier and voice operated gain ad-

justing 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 external components.
