Explain explanatory notes on A/D conversion.

The digital inventory is working a revolution into the field of microcontrollers, technology and microprocessors are used more efficiently than those of analog circuitry. Although the output of any sensors that deals with physical equality as temperature, pressure, humidity, velocity and viscosity that are, used most of the data acquisition flat types are in the form of continuous signals or analog signals.

Microcontrollers and microprocessors are doing nothing along with these signals. As they need the signal in the form of binary numbers. Therefore we should convert these analog signals in digital format. The given popular ways are used for Analog to Digital conversion.

• Flash ADC
• Digital Ramp ADC
• Successive Approximation ADC
• Tracking ADC
• Slope (Integration) ADC.
