The advantage of parallel or flash converters is that they are simple to construct and do not require any timing clocks as the instant an analogue voltage is applied to the comparator inputs, it is compared against a reference voltage.

Parallel of “Flash” A/D converters use a series of interconnected but equally spaced comparators and voltage references generated by a series network of precision resistors for generating an equivalent output code for a particular n-bit resolution. One simple and easy way is by using parallel encoding, also known as flash, simultaneous, or multiple comparator converters in which comparators are used to detect different voltage levels and output their switching state to an encoder. The process of taking an analogue voltage signal and converting it into an equivalent digital signal can be done in many different ways, and while there are many analogue-to-digital converter chips such as the ADC08xx series available from various manufacturers, it is possible to build a simple ADC using discrete components.
So how can we convert a continously changing signal with an infinite number of values to one which has distinct values or steps for use by a digital circuit. Then we can see that the major differences between an analogue signal and a digital signal is that an “Analogue” quantity is continuously changing over time while a “Digital” quantity has discrete (step by step) values. Finer output voltage levels could easily be produced by using a multi-positional switch and increasing the number of resistive elements within the potential divider network, therefore increasing the number of discrete switching steps. So for example, the output voltage will be 2 volts, 3 volts, 5 volts, etc. Thus an analogue to digital converter takes an unknown continuous analogue signal and converts it into an “n”- bit binary number of 2 n bits. The number of binary digits, or bits used to represent this analogue voltage value depends on the resolution of an A/D converter.įor example a 4-bit ADC will have a resolution of one part in 15, (2 4 – 1) whereas an 8-bit ADC will have a resolution of one part in 255, (2 8 – 1).
So it is necessary to have an electronic circuit which can convert between the two different domains of continuously changing analogue signals and discrete digital signals, and this is where Analogue-to-Digital Converters (A/D) come in.īasically an analogue to digital converter takes a snapshot of an analogue voltage at one instant in time and produces a digital output code which represents this analogue voltage. While analogue signals can be continuous and provide an infinite number different voltage values, digital circuits on the other hand work with binary signal which have only two discrete states, a logic “1” (HIGH) or a logic “0” (LOW). In the real world, analogue signals have continuously changing values which come from various sources and sensors which can measure sound, light, temperature or movement, and many digital systems interact with their environment by measuring the analogue signals from such transducers. S.The Analogue-to-Digital Converter, (ADCs) allow micro-processor controlled circuits, Arduinos, Raspberry Pi, and other such digital logic circuits to communicate with the real world.
