A/D Converter and Its Needs

What is A/D Converter?

A/D Converter is Electronic integrated circuit which transforms signal from analog (continuous) to digital (discrete) form. Analog signals are directly measurable quantities and Digital signals contain only two states and for digital computer, we refer to binary states 0 or 1.

An Analog to Digital Converter is a very useful feature that converts an analog voltage on a pin to a digital number. The input to an analog to digital converter (A/D) consists of a voltage that varies among a theoretically infinite number of values. After converting from the analog world to the digital world we can begin to use electronics to interface to the analog world around us. Analog Devices A/D converters feature a variety of breakthrough capabilities enabling new system architectures that meet customer needs. Low powers, low cost and compact design, are required by today’s systems.

Amsyx offers the industry’s largest range of A/D converter products that design engineers depend on for reliable performance in the harshest environments, both on Earth and in space. If you are looking for high quality and improving efficiency reliability while lowering cost and consider using the industry’s number one A/D converter products from Analog Devices.

Why A/D Converter is needed?

Microprocessors can only perform complex processing on digitized signals. When signals are in digital form they are less susceptible to the deleterious effects of additive noise. A/D Converter provides a link between the analog world of transducers and the digital world of signal processing and data handling.

Application of ADC: - A/D Converter are used virtually everywhere where an analog signal has to be processed, stored and transported in digital form. Some examples of A/D Converter usage are digital volt meters, thermocouples, cell phone, and digital oscilloscope. Micro controllers commonly use 8, 10, 12 and 16 bit A/D Converters,


When an A/D Converter chip returns 16 bits, it is probably better than a 12-bit A/D converter, but not always.  The simple fact that a converter returns 16-bits says little about the quality of those bits. It is hard to simply state "the resolution" of a given device.

What we like to do, is provide actual measured data that tells you the resolution of a device including typical inherent noise.16-bit A/D converter designed for digitizing high frequency and wide dynamic range signals up to input frequencies of 700MHz. The input range of the A/D Converter can be optimized with the PGA front end.

Integrated Circuit Features and Availability



An integrated circuit, or IC for short form, is a combination of electronic circuits on a tiny plate of semiconductor material and functions as the core part for all types of electronic equipment in use world widely nowadays. In fact, integrated circuits have made revolution in the field of electronics. In 21st century computers, mobile phones, and other digital appliances and instruments are a mainstream essential. They are present in every aspect of people's daily routine and it can be said that 21st century world as we know it would nothing without the presence of these mostly used devices. The latest age is made possible due to the reliable-cost of these circuits, which makes such devices cost-effectively possible.

Technology has advanced considerably over the years, which is important news for the electronics revolution. Presently, the most superior integrated circuits are microprocessors, which have the tendency to control everything from computers to cell phones to digital microwave ovens. Along with this, digital memory chips are also very central to the modern information culture of today. The cost of developing a composite integrated circuit is in fact high, but the cost is reduced greatly when production is extended across millions of units. ICs have slowly become slighter, which allows high circuitry to be packed on each small chip. Up to number of transistors and other electronic components can be adjusted into an area that is no larger than a fingernail. The size of each circuit was near about 100 nanometers in 2008, and is now at ten times lesser in 2013.

Nowadays electronic devices have become an essential part of our daily living. Devices such as cell phones, computers. PDAs, laptops, music players, and many more things, have become an important part of our lives making the idea of sustaining without their aid seem to be simply impractical. Whenever there is any break down with any of our beloved devices, at times we are able to get it repaired by minor changes and software updates; however, many times we are required to get a defective part replaced.

When looking to buy replacement parts, the main concerns for most of us are accessibility, authenticity and cost. Even though finding an electronic parts store may not be quite hard, finding an appropriate store can be. Especially when looking to buy parts for old models of electronic devices such as iPhone 2G parts, 3G parts, the accessibility can be the major worry. To add to the despair, fake electronics' market is supplying fake substitute parts in bulk to every part of the world, making the task of finding authentic parts extremely difficult. In addition, if you buy components such as iPod classic parts from company outlets, the prices are always way too much. All these factors make the task of finding suitable parts awfully difficult.
