Application of adc

ADC stands for analog to digital converter. It is an electronic device used for converting an analog signal into a digital signal. The analog input signal of ADC is continuous time & continuous amplitude signal. The output of ADC is a discrete time and discrete amplitude digital signal.

Which ADC is mostly used in applications?

The successive-approximation ADC is by far the most popular architecture for data-acquisition applications, especially when multiple channels require input multiplexing.

What are the major applications of dual slope type ADC?

The dual slope ADC is used in the applications, where accuracy is more important while converting analog input into its equivalent digital (binary) data.

What are the application of DAC?

DACs are commonly used in music players to convert digital data streams into analog audio signals. They are also used in televisions and mobile phones to convert digital video data into analog video signals. These two applications use DACs at opposite ends of the frequency/resolution trade-off.

What is the advantage of ADC?

ADCs employ a number of techniques to optimize application performance, including traffic identification, data compression and reverse proxy caching. ADCs also offer Secure Sockets Layer encryption and protection against distributed denial-of-service attacks.

How do I select my ADC application?

ADC Selection Criteria to Consider

Resolution refers to the number of output bits that the ADC can generate per conversion.
Speed has to do with the device's sampling rate – in other words, what is the highest number of conversions per second that the ADC can handle? ...
Accuracy is relatively straightforward.

What are types of ADC?

There are really five major types of ADCs in use today:

Successive Approximation (SAR) ADC.
Delta-sigma (ΔΣ) ADC.
Dual Slope ADC.
Pipelined ADC.
Flash ADC.

Which is the fastest ADC?

Flash ADC (Fastest) The flash ADC is the fastest type available. A flash ADC uses comparators, one per voltage step, and a string of resistors.

What is ramp type ADC?

A ramp-type analog-to-digital converter (also known as ramp-compare or time-base ADC) comprises five basic circuits: a ramp generator, a counter, a comparator circuit, a clock pulse generator, and a gate circuit, which are simultaneously operated to provide analog-to-digital conversion.

Why it is called dual slope ADC?

In dual slope type ADC, the integrator generates two different ramps, one with the known analog input voltage VA and another with a known reference voltage –Vref. Hence it is called a s dual slope A to D converter.

What is the difference between single slope ADC and dual slope ADC?

Single slope ADC (Integrated ADC ) Dual slope ADC is preferred over the single slope analog to digital converter. For a clear conception of the dual-slope ADC, we will study the single slope first. It consists of an integrator and a comparator.

Why do we need ADC and DAC?

Since analog and digital signals are inherently different in nature, a device is needed to convert them from one to another. These devices are called DACs (Digital to Analog Converter) and ADCs (Analog to Digital Converter). These devices do as their name implies; they convert digital signals to analog and vice versa.

What is the purpose of digital to analog converter?

A digital to analogue converter (DAC) converts a digital signal from the computer into an electrical voltage which can be used to drive electrical equipment, for example, a stirrer motor.

What is an example of DAC?

An example of a DAC device is a modem. A modem requires DAC to convert data to analog signals, which can be carried by a telephone wire. Another example of a DAC device is a video adapter.

What are the advantages and disadvantages of ADC?

Low supply voltage, low power consumption, high sampling rate, circuit simplicity and easy integration on chip are main advantages. Main disadvantages are noise, low dynamic range and nonlinearity.

What are the specifications of ADC?

How do we use analog and digital signals in everyday life?

There are two main types of signals used in electronics: analog and digital signals. ... Analog and Digital Signals: Systems and Applications

Audio recording and reproduction.
Temperature sensors.
Image sensors.
Radio signals.
Telephones.
Control systems.

Why flash type ADC is fastest?

A flash type ADC produces an equivalent digital output for a corresponding analog input in no time. Hence, flash type ADC is the fastest ADC.

Which ADC is more accurate?

Dual slope integration type ADC has the highest accuracy.

What is ADC resolution?

Resolution. The ADC resolution is defined as the smallest incremental voltage that can be recognized and thus causes a change in the digital output. It is expressed as the number of bits output by the ADC. Therefore, an ADC which converts the analog signal to a 12-bit digital value has a resolution of 12 bits.
