An Analog to Digital Converter (ADC) is used in data processing for the transforming analog electrical signals (such as light entering a digital camera) into a digital signal. These data converters are used in various fields like communications, energy, healthcare, automation, aerospace/defense, etc. Analog signals could be called real world signals like temperature, pressure, voltage, current, distance, etc. and ADC converts them into digital signal can then be processed, changed, calculated, transmitted or stored.
Market for ADCs
To meet the global demandthe analog-to-digital converters market is growing at a steady pace with the compound annual growth rate of 8.7%. demand is maintained by digital fields such as communication and medical imaging which are the driving factors of the market. Due to these factors and many more the global market for ADCs was USD 2165 million last year and is expected to increase to USD 3287 million by 2021. North America holds for the biggest market share in the global ADC market due to its advanced technology and acceptance in the countries. Asia Pacific on the other hand has maximum potential for the revenue growth of ADC market.
Uses of ADCs
Different types of ADCs
With usage in different kinds of areas, the ADCs needed to be especially made for specific purposes, for example the ADC which measures the temperature can’t record sound or calculate the intensity of light. Hence the various kinds of ADCs and various methods of using them like-
A last word
Commercially the ADCs are used as ICs or integrated circuits. Generally the most expensive part of such a device is the pins. A revolution happened in ADC industry in February 2002 when Mega- and giga-sample per second converters were made available. These converters are used in high-tech digital cameras and TV tuner cords.
