 Amplifier IC

What is the use of an Amplifier IC?

The function of an Amplifier IC is to increase the current, voltage or power of a signal flowing through a piece of electrical equipment.

How do you choose the Best Amplifier IC?

You need to consider the following factors when selecting an Amplifier IC:

Amplifier integrated circuit

· Heat management

The size of the Amplifier IC reduces the sizes of the components while increasing their number.

This has the effect of producing a lot of heat which can affect the performance of electrical equipment.

You, therefore, need to check on the amplifier heat management before purchasing your amplifier IC.

· Speed performance

The arrangements of the components of the amplifier IC should not interfere with the speed performance of your electrical gadget.

Technologies such as bumping technology allow for high performance while minimizing wire bond interference.

· Thermal expansion

The thermal expansion rate for the amplifier IC should be the same.

This prevents the effect of the components disintegrating due to different changes in temperature.

· Dielectric loss

Dielectric loss affects the quality of the signal transmission for your amplifier IC.

You need to select an amplifier IC with less dielectric loss.

· Water-resistant

An effective amplifier IC should be water-resistant.

This helps in preventing dielectric loss and the dielectric constant of your electrical device.

What are the Characteristics of Audio Amplifier IC?

Some of the main characteristics of these IC chips include:

· The input offset voltage

This is the voltage applied between two input terminals on the null to op-amp output of the audio amplifier.

· Difference input resistance

This is the equivalent resistance measured from any input terminal while there is ground maintenance of the other input terminal connections.

· Input capacitance

This is the equivalent capacitance measured from any input terminals, while there is ground maintenance of the other input terminal connections.

· Supply voltage rejection ratio

Supply Voltage Rejection Ratio refers to the difference in the op-amp’s offset voltage.

The difference in supply voltage causes this.

· Slew Rate

This is the maximum rate of variation of the output voltage per unit time.

It is an important feature when selecting the op-amp of high frequencies.

· Large Signal Voltage Gain

This refers to the ratio between the voltage difference between two input terminals and the output voltage.

· Power dissipation

It is a measure of the power consumption by the semi-conductors during the maximum driving of all the inputs.

· Noise margin

It refers to the maximum noise voltage in addition to an input signal of an audio amplifier IC.

This noise margin does not have a considerable change in the output of the circuit.

· Operating temperature

The semi-conductors of the amplifier IC are temperature sensitive.

The operating temperature is the temperature at which there is an optimum performance of the IC.

How do you Test Amplifier IC?

An Amplifier IC undergoes the following tests:

1. Continuity test

This is a test that measures if there is electricity flow through a given part.

To conduct this test, place the two probes to the multimeter and select continuity.

The results are positive if the readings on your multimeter are zero.

If it records one or it has an open loop, then there is no continuity at the given part.

2. Resistance test

Resistance tests are a measure of current loss while there is a flow of electricity through a given component.

Its unit for measurement is Ohms.

You can determine the resistance of a given component using a multimeter.

Set the multimeter to read the resistance range on the amplifier IC.

Then check if the given point can handle the resistance range on the amplifier IC.

3. Voltage test

The voltage test measures the force of electric pressure.

Carrying out this test depends on the type of current your appliance requires, that is, direct current or alternating current.

To carry out this test, adjust the multimeter to read the voltage set out on the appliance.

You then check if the amplifier IC can handle the expected voltage range.

4. Leakage test

This test determines if the amplifier IC has damages or not.

For this, you need to observe keenly on the sides of the amplifier IC to check for any damages.

What is Feedback Amplifier IC?

Feedback Amplifier IC refers to the injection of a fraction of the output energy of an amplifier IC back to its input.

There are two types of amplifier feedback IC.

· Positive feedback amplifier IC

This is where the injected energy aids the input signal since they are in phase with each other.

The injected energy can either be current or voltage.

· Negative feedback amplifier IC

In this type of feedback, the injected energy is out of phase with the input signal.

As a result, the injected energy opposes the input signal.

The negative feedback energy can either be voltage or current.

The advantages of negative feedback include; noise and distortion reduction, an increase in input impedance, and a decrease in output impedance.

Negative feedback is an important consideration during the fabrication process of an amplifier IC.

What are the Benefits of Amplifier ICs?

Amplifier IC

The benefits of an Amplified IC are:
