You will have to determine its scaling factor. The output of the ADC is a number, you can interpret it anyway that is necessary for the system it is in.
Counter type ADCOne of the simplest types of the ADC is the Counter type ADC. The input signal of the ADC is connected to the signal input of its internal comparator. ADC then systematically increases the voltage on the reference input of the comparator until the reference becomes larger than the signal & the comparator output goes to zero.Fig.1 Counter type ADCDinesh Kumar - http://harshit.org
There is no formal adc input on the 8051. However, the CMOS version of the chip can use a technique involving a resistor, diode, and capacitor, along with a bidirectional pin (or one output pin and one input pin) to implement a "quick and dirty" adc function. You discharge the capacitor and then let it charge to the voltage of the input. You measure the time it takes to see the input pin change, and you calculate the input voltage.
they are same expect error .in adc0809 1/2 lsb unadjusted error is present and in adc 0809 1lsb error is present.
If you are using XILINX FPGA, try to insert a Microblaze processor to control your ADC.
flash type ADC is fastest because in it change takes place simultaneously not sequentially time taken for conversion is 100 ns.
The voltage at which the adc converts the signal.... it can also be called a limit of an ADC.
The current amplification factor, ADC, is calculated by dividing the output current by the input current in a circuit. It represents how much the current signal is amplified in the circuit. ADC can be expressed as the output current divided by the input current (ADC = I_out / I_in).

Types Of ADC Are As follows: 1.Counter type ADC 2.Successive approximation type ADC 3.Flash Type ADC 4.Wilkinson type ADC
An analog-to-digital converter (abbreviated ADC, A/D or A to D) is a device that converts a continuous quantity to a discrete digital number. The reverse operation is performed by a digital-to-analog converter (DAC).Typically, an ADC is an electronic device that converts an input analog voltage (or current) to a digital number proportional to the magnitude of the voltage or current. However, some non-electronic or only partially electronic devices, such as rotary encoders, can also be considered ADCs.The digital output may use different coding schemes. Typically the digital output will be a two's complement binary number that is proportional to the input, but there are other possibilities. An encoder, for example, might output a Gray code.An ADC might be used to make an isolated measurement. ADCs are also used to quantize time-varying signals by turning them into a sequence of digital samples. The result is quantized in both time and value

The abbreviation, ADC in customs clearance process can mean several things. It can mean Automated Data Capture, which means that a package was inspected with an automated device. ADC can also mean Additional Collection is warranted when a package has arrived by air.
