![]() ![]() The block diagram of ADC is shown below which includes sample, hold, quantize, and encoder. Classification of ADCs based on factors like performance, bit rates, power, cost, etc. Dynamic characteristics of the high-performance ADCs are improved measurement repeatability, low power consumption, precise throughput, high linearity, excellent Signal-to-Noise Ratio (SNR), and so on.Ī variety of applications of the ADCs are measurement and control systems, industrial instrumentation, communication systems, and all other sensory-based systems. With the invention of a wide variety of ADC integrated circuits (IC’s), data acquisition from various sensors becomes more accurate and faster. One of the major benefits of ADC converter is the high data acquisition rate even at multiplexed inputs. Bit resolution is nothing but how much accuracy can an analog to digital converter can convert the signal from analog to digital.The sample rate of an ADC is nothing but how fast an ADC can convert the signal from analog to digital.(1999), "Analog-to-digital converter survey and analysis", IEEE Journal on Selected Areas in Communications, 17 (4): 539–550, doi: 10.1109/49.

The size of the number grows with an increase in the input voltage or current. Typically, an ADC is an electronic device that converts an input analog voltage or current to a digital number. The reverse operation is performed by a digital-to-analog converter ( DAC). ![]() An ADC may also provide an isolated measurement. ![]() ![]() 4-channel stereo multiplexed analog-to-digital converter WM8775SEDS made by Wolfson Microelectronics placed on a X-Fi Fatal1ty Pro sound card.Īn analog-to-digital converter (abbreviated ADC, A/D or A to D) is an electronic integrated circuit that converts a continuous quantity to a discrete time digital number. ![]()
