The design of the amplifier is straightforward: a power op-amp followed by two output transistors. The supply current to the IC varies in accordance with the input signal.

Consequently, there will be a similarly varying voltage drop across resistors R6, R7, R8, and R9 since these are in the supply lines to the op-amp.

As long as the current is lower than about 1A, the voltage drop across the resistors will be insufficient to switch on transistors T1 and T2.

This means that outputs up to 2 W into 4 ohm are provided entirely by the op-amp. Once the output current exceeds a level of 1A, the transistors are on and contribute to the power ….Incorporates well matched, high-voltage JFET and bipolar transistors in a. No Signal. No Load.

To terminate the Op-Amp the Inverting pin of the Op-Amp is connected to the Output pin and the Non-Inverting pin is provided with a constant voltage source. The Op-Amps as we know are the work horse for most electronics circuit designs. There are a plethora of application circuits for Op-Amp each tp its characteristics and significance in its own way.

A Closed-Loop system provides feedback to the input this limiting the gain value of the Op-Amp and the noise associated with it. Product is in volume production 0. Applications Circuit requiring high input impedance Buffer application Filter circuits, Voltage tl Integrator, Differentiator, Summer, adder, Voltage follower, etc.

TL074 Quad Operational Amplifier

This site uses cookies: Find out more. Ok, No Problem.The proposed 10 band graphic equalizer circuit can be used in conjunction with any existing audio amplifier system to get an enhanced 10 stage audio processing, and customized tone control. The circuit can be easily converted to a 5 band graphic equalizer by simply eliminating 5 stages from the shown design. The unit is quite simple to use. All one has to do is feed the TV or PC audio input to this circuit and hook the output with the existing home theater amplifier.

Next, it would be just a matter of adjusting the given 10 band controls and enjoying the vastly improved sound quality. You would be able to tailor the sound as per your preferred tastes.

As an example, the midrange controls of the equalizer can be adjusted to highlight dialogue or in order to reduce the harshness over a particular range of voice audio. Or perhaps you can roll off the high pitched even to further extents in case you wished, or simply heightened the bas boost to your liking. The circuit also includes a fixed 10kHz low pass filter stage for cancelling out unwanted noise such as hiss or other high frequencies disturbances.

Referring to the given circuit diagram we can see that the associated opamps form the main active component responsible for the required optimizations. You will notice that all the 10 stages are identical, it's the difference in the values of the incuded capacitors and the pot which effectively varies the processing leves across the various stages. For analyzing the operation we may consider any one of the opamp stages since all of them are identical. Here the opamps act as " gyrators " which refers to an opamp circuit which effectively converts a capacitive response to an inductance response.

Consider an AC voltage source Vi connected to the opamp stage.

This pushes a current Ic via the capacitor C1, C2, C3 etcwhich constitutes a proportional voltage across the connected ground resistance R11, R12, R13 etc. Due to this the voltage across the feedback resistor R1, R2, R3 etc becomes equal to the difference between Vin and Vout which causes current to flow via the feedback resistor and back into the input voltage source!

A careful assessment of the phases of the above developed current would show that as Ic leads the voltage Vin as it can expected for any capacitive circuit the net input current that may be the vector sum of Ic and Io in fact trails the voltage Vi. Therefore this implies that in effect, the capacitor C has gotten transformed into a virtual inductor due to the actions of the opamp. Here C would be in Farads and the resistances in Ohms.

The pots effectively vary the input current to the opamps which results in a change in the value of the above explained "inductance", which in turn results in the required music enhancement in the form of treble cuts or bass boosts. A very neat and reasonably efficient 5 band graphic equalizer circuit using only passive components can e built as shown in the following diagram:.

As can be seen in the figure above, the 5 band equalizer has five potentiometers for controlling the tone of the input music signal, while the sixth potentiometer is positioned for controlling the volume of the sound output. Basically, the shown stages are simple RC filters, which narrow or broaden the frequency passage of the input signal, so that only a certain band of frequency is allowed to pass, depending on the adjustment of the relevant pots.

Lastly followed by the volume control pot control. Since the design does not use active components this equalizer is able to operate without any supply input.

TL074 Application Circuit and TL074 Pinout

Please note that if this 5 band equalizer is implemented for a stereo or multichannel system, it may become necessary to set up an equalizer in the identical manner for each of the channels. If you have any circuit related query, you may interact through comments, I'll be most happy to help!
