Simple Analog To Digital Converter Circuit. Typically analogue to digital converter a d converter adc requires interfacing through a microprocessor to convert analogue information into digital format. Thus the capacitor c2 is charged by the reference voltage vref that through s1 and r2.
User can use only one input channel at a time and the channel selection was done by using the pins adda to addc. This ic was a simple analog to digital converter which provides a resulting 8 bit data for input analog signal. Analog signals are directly measurable quantities.
Then as suggested use a uc setup as a comparator circuit.
User can use only one input channel at a time and the channel selection was done by using the pins adda to addc. The pins out1 to out8 gives the output data bits in binary form whereas in0 to in7 allows user to feed their analog signal. Schematic diagram of analog to digital converter circuit. Most of the adcs take a voltage input as 0 to 10v 5v to 5v etc and correspondingly produces digital output as some sort of a binary number.
