Having two devices in the same package saves parts and and cost. The pin functions for both devices are shown the the right. ![]() Another common example would be a TL082 which is a component with two separate devices within the same package. The 741 is an example of a common Opamp having a single device within the package. The amplifier could be constructed of either two individual Opamps or a package containing two Op Amps. Or a separate potentiometer could be added into each channel so that each channel would be adjusted up or down, with regard to the other. A separate balance control could also be added to change the volume of one channel, while reducing the other. So although each channel uses a different potentiometer they both move up or down at the same time producing a volume control. Note that the two potentiometers are ganged together, one knob changes both potentiometers at the same time. However to the right, some different pin numbering is shown. The schematic does not show pin numbers for the Op Amps because the circuit works for either a single or dual package Op Amp and of course a large number of different Op Amps. In some cases the component may be called a ganged stereo taper. A dual ganged 100K-Ohm audio-taper potentiometer should be used over a linear taper or potentiometer. Of course the 100k potentiometers set the voltage level reaching the Op Amps. Stereo AmplifierĪ typical non-inverting Op Amp configuration. The circuit is shown with minimum components and can be used with op amps using a single or split voltage supply. This is an example of a stereo amplifier circuit, dual channel. ![]() Electrical Engineering Dictionary "A" "B" "C",
