8051 is old MCU technology there is other MCUs on the market with build in ADCs, the PIC MCU from Micro Chip is the most popular and is very easy to program, more about PIC at this link http://www.patenttrade.net
The simplest way would be via an ADC
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.
The ADC0804 is named based on its specifications, where "0804" indicates the number of bits and the type of architecture. Specifically, "08" signifies that it is an 8-bit analog-to-digital converter, meaning it converts analog signals into a digital format with 256 possible values (from 0 to 255). The "04" typically refers to the specific model or version of the ADC within a series produced by the manufacturer, distinguishing it from other variants or models with different specifications.
Types Of ADC Are As follows: 1.Counter type ADC 2.Successive approximation type ADC 3.Flash Type ADC 4.Wilkinson type ADC
Answer It is both 8 bit processors in a 40 pin package but it is not pin compatible, it have almost the same functions but it is very difficult to compare the two because it is not the same family.
The voltage at which the adc converts the signal.... it can also be called a limit of an ADC.
