Suppose there is a system consisting of temperature sensor, ADC, DAC and a Fan. The   temperature sensor gives output as voltage value. As the temperature increases more than 18°C it produces the voltage of 8.17 V. That voltage is then put through a 4-bit Successive Approximation ADC as input. After that the output of that ADC is applied to a 4-bit R/2R- ladder DAC to produce enough voltage to turn ON the fan. Take R=”Group#” KΩ. Consider logic “1” as 7 V and logic “0” as 2V. (i) Illustrate the block diagram for the system showing ADC, DAC, Fan and temperature sensor. (ii) Design the circuit diagram with ADC & DAC for the complete system showing necessary parameters value.

Analog to Digital Converters

The analog-to-digital converter (ADC) allows circuits controlled by microprocessors, Arduinos, Raspberry Pi, and various reasonable digital circuits to be connected to the real world. In the real world, analog signals have a continuous stream of information from a variety of sources and sensors capable of measuring sound, light, temperature, or movement, in addition to the many digital systems that interact with their environment by measuring analog signals from those transducers.
