VOLTAGE_CONTROLLED_AMPLIFIER

Published:2009/6/23 2:04:00 Author:Jessie | From:SeekIC

This circuit is basically an op amp with an extra input at pin 5. A current Ltac is injected into this input and this controls the gain of the device linerly. Thus by inserting an audio signal (±10 mV) between pin 2 and 3 and by controlling the current on pin 5, the level of the signal output (pin 6) is controlled.
