ADC: Analog-to-Digital Converter

ADC is an abbreviation of "Analog-to-Digital Converter".

An analog-to-digital converter (ADC, A/D, or A-to-D) is a system that converts a signal of analog, such as a sound pulled out up by a microphone or light inwardly bounded towards a digital camera, into a digital signal in the field of electronics. An ADC may also make available an inaccessible measurement such as an electronic device that converts an input analog voltage or current to a digital number symbolizing the magnitude of the voltage or current. Normally the digital output is a two's complement binary number that is proportional to the input; however, there are further prospects or chances.

There are quite a lot of ADC architectures. Due to the complication and the requirement for accurately corresponding modules, the entirely however the mainly specialized ADCs are put into operation as integrated circuits (ICs).

A digital-to-analog converter (DAC) carries out the reverse function task; it converts a digital signal into an analog signal.

ADC Applications

  • Music recording:
    In the 2000s era of music, Analog-to-digital converters are very vital to music reproduction technology and digital audio workstation-based sound recording. In progress, the up to date crop of analog-to-digital converters made use of in music can sample at rates up to 192 kilohertz.
  • Digital signal processing:
    ADCs are essential to process, accumulate, or convey virtually any analog signal in digital form. TV tuner cards, for example, make use of rapid video analog-to-digital converters.
  • Scientific instruments:
    Digital imaging systems generally use analog-to-digital converters in digitizing pixels. Several radar systems generally use analog-to-digital converters to convert signal strength to digital values for succeeding signal processing.
  • Rotary encoder:
    A range of non-electronic or only partially electronic devices, such as rotary encoders, can also be regarded as ADCs. Normally the digital output of an ADC will be a two's complement binary number that is proportional to the input.
  • Testing:
    Testing an Analog to Digital Converter needs an analog input source and hardware to send control signals and take into control digital data output. A range of ADCs also needs a precise source of the reference signal.

The main factors to test a SAR ADC are:

  • DC offset error
  • DC gain error
  • Signal to noise ratio (SNR)
  • Total harmonic distortion (THD)
  • Integral non linearity (INL)
  • Differential non linearity (DNL)
  • Spurious free dynamic range
  • Power dissipation
