1) (60 pts) A temperature sensor is connected to an ADC0804 and the output of the ADC0804 is read by an 8051 to calculate the temperature. The temperature sensor produces an output of 0.001V (1 mV) per 0.1 Celsius degree ( o C) of temperature. (V out =0.001 x (T/0.1) V, where T =temperature in o C. ) ADC0804 is connected according to two different configurations. In Configuration 1, Vref/2 pin is left floating (not connected) and Vin(-) pin is connected to ground. In Configuration 2, Vref/2 is connected to a 1V supply and Vin(-) is connected to a 0.1V supply. Assuming that the temperature that will be measured remains between 20 and 100 o C, answer the following questions: a) (30pts) For each configuration
