Voltage controlled amplifier


Posted on Apr 29, 2012

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