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 external components. MAIN AMP OUTPUT MAIN AMP INPUT 7 0V 6 5 PREAMP INPUT PREAMP INPUT 4 3 V CC 8 1 2 PREAMP OUTPUT AGC TIME CONST CM8 Fig.
