Voltage controlled amplifier ic.

The vca810 is a dc coupled wideband continuously variable voltage controlled gain amplifier. Figure 8 shows how two amplifiers of the figure 7 type can be used together to make a voltage controlled stereo amplifi er. Things that can force changes to this circuit are many but are mostly limited to larger and smaller input signals and higher or lower supply voltage ranges. Vcrs manufactured in this way can be obtained as.

They are very high performance current in current out devices with two opposing polarity voltage sensitive control ports. This voltage controlled amplifier circuit is simply an op amp having an additional input at pin 5. The higher the control voltage the more signal is passed. 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.

The ic ideal for use in stereo amplifier applications. That 2180 series integrated circuit voltage controlled amplifiers vcas are very high performance current in current out devices with two opposing polarity voltage sensitive control ports. They offer wide range exponen tial control of gain and attenuation with low signal distortion. This voltage controlled amplifier is fully functional and tested.

This modern designed vca is based on the that 2181 series integrated circuit voltage controlled amplifiers vcas. The device provides a differential input to single ended output conversion with a high impedance gain control input used to vary the gain over a 40 db to 40 db range linear in db v. The vcr is one of the numerous interesting circuit elements that can be produced by using a jfet junction field effect transistor with simple biasing. Note in this case that the i bias gain control pins of the two otas are shorted together and fed from a single gain control voltage and current limiting resistor.

The soundlazer vca offers a wide range exponential control of gain and attenuation with low signal distortion. A current ilsc is inserted into this input which controls the gain of the device linerly. The part delivers great performance in a tiny package offering 118db dynamic range 130db gain control range and distortion under 0 1 without any adjustment. The amplifier can achieve an 80 db dynamic control range with less than 0 2.

A simple linear voltage controlled amplifier can be constructed with one op amp and two jfets see the figure. That corporation unveils the new that 2162 the company s first dual blackmer voltage controlled amplifier vca ic. At some voltage level the entire signal is let through.
