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,

16bit analog to digital converter

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.
