What is an Analog to Digital Converter?

An analog-to-digital converter, or ADC, converts analog (continuously variable) signals into digital (multi-level) signals without altering their essential content. The analog information is transmitted by modulating a continuous transmission signal and by amplifying the strength of the signal or varying its frequency in order to add or subtract data. The input to an analog-to-digital converter consists of a voltage which varies among a theoretically infinite number of values. The output of the ADC however has defined levels or states. The simplest digital signals only have two states and are therefore called binary. Digital signals are transmitted in a more efficient way than analog signals because well-defined digital impulses are easier for an electronic circuit to distinguish than chaotic noise. This is the main advantage of digital communications.

Types of Analog to Digital Converters

There are many different kinds of analog to digital converters and at Future Electronics we stock many of the most common types categorized by resolution, number of channels, supply voltage, interface, packaging type and power consumption. The parametric filters on our website can help refine your search results depending on the required specifications.

The most common sizes for resolution are 8 b, 10 b and 12 b. We also carry analog to digital converters with resolution up to 24 b. Supply voltage can be from -9 V to 22 V, with the most common size being 2.7 V to 5.5 V.

Applications for Analog to Digital Converters:

Computers use analog-to-digital converters in order to convert signals from analog to digital before they can be interpreted. For example, a modem will convert signals from digital to analog before transmitting them over telephone lines that carry only analog signals. These signals are then converted back into digital form at the receiving end so that the computer can interpret the data in digital format. In a digital signal processing system, an ADC is required if the input signal is analog. For example, a fast video ADC is used in TV tuner cards. 8, 10, 12, or 16 bit analog to digital controllers are common in microcontrollers. They are also needed in digital storage oscilloscopes. Analog to digital converters are used in music reproduction technology when done using computers. In such an application, an ADC is needed when an analog recording is used in order to create the PCM data stream that goes onto a CD or a digital music file.

Choosing the Right Analog to Digital Converter:

When you are looking for the right analog to digital converters, with the FutureElectronics.com parametric search, you can filter the results by various attributes: by Number of Channels (1, 2 ,3 , …), Interface (Parallel, Serial, Spi, …) and Supply Voltage (from -9 V to 22 V) to name a few. You will be able to find the right chip for your ADC devices such as an audio or video analog to digital converter, TV analog to digital converter, USB analog to digital converter, analog to digital converter circuit or any other device that converts an analog signal to a digital signal.

Analog to Digital Converters in Production Ready Packaging or R&D Quantities
