Type of analog to digital converter7/4/2023 ![]() ![]() Instead, we use an ADC to convert the analog voltage input to a set of bits that can be directly connected to the microprocessor's data bus and used for computation. If we link this directly to a digital input, depending on the input thresholds, it will register either as high or low, which is completely useless. For example, a temperature sensor such as the LM35 outputs a temperature-dependent voltage, in the case of that particular unit, 10 mV per degree of temperature increase. Unfortunately, the world in which we live is still analog and full of color for digital systems, not just black and white. Today's electronics are solely digital the good old days of analog computers are gone. These ADC circuits can be found on their own as individual ADC ICs or integrated into a microcontroller. Ⅱ Definition of ADC (Analog to Digital Converter)Ī circuit that converts a continuous voltage value (analog) to a binary value (digital) that can be interpreted by a digital computer that could then be used for digital computing is an analog to digital converter.
