Analog-to-digital converter

An analog-to-digital advocate (abbreviated ADC, A/D or A to D) is a accessory that converts a connected abundance to a detached time agenda representation. An ADC may aswell accommodate an abandoned measurement. The about-face operation is performed by a digital-to-analog advocate (DAC).

Typically, an ADC is an cyberbanking accessory that converts an ascribe analog voltage or accepted to a agenda amount proportional to the consequence of the voltage or current. However, some non-electronic or alone partially cyberbanking devices, such as rotary encoders, can aswell be advised ADCs.

The agenda achievement may use altered coding schemes. Typically the agenda achievement will be a two's accompaniment bifold amount that is proportional to the input, but there are added possibilities. An encoder, for example, ability achievement a Gray code.
