Voltage Controlled Amplifier Design. Designing a voltage controlled current source by the same rule let s see the below circuit. Thus by inserting an audio signal 10 mv within pin 2 and 3 and with controlling the current on pin 5 the amount of the signal output pin 6 is controlled.
Designing a voltage controlled current source by the same rule let s see the below circuit. 14 to 14 db gain sta 2a dual high gain line amplifiers std 10k passive audio divider combiner 10 kω. Vcas have many applications including audio level compression synthesizers and amplitude modulation.
A variable gain or voltage controlled amplifier is an electronic amplifier that varies its gain depending on a control voltage.
They also have application notes on how to make them more linear with circuit configurations. A variable gain or voltage controlled amplifier is an electronic amplifier that varies its gain depending on a control voltage. This voltage controlled amplifier circuit is simply an op amp having an additional input at pin 5. A crude example is a typical inverting op amp configuration with a light dependent resistor in the feedback loop.
