Question

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.
