TECHNICAL DATA
GAIN CONTROLLED MICROPHONE PREAMPLIFIER/VOGAD
The KL6270 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.
FEATURES • Constant Output Signal • Fast Attack • Low Power Consumption • Simple Circuitry
APPLICATIONS • Audio AGC Systems • Transmitter Overmodulation Protection • Tape recorders
QUICK REFERENCE DATA • Supply Voltage: 4.
