Design the ADC interface to a digital thermostat using an LM34 temperature sensor and the ADC0804. Your system must measure accurately (±0.2°F) from 50 to 101°F. The LM34 puts out 0.01 V per degree F(0°F = 0°V).

(a) What should the digital value for 50°F be for the best resolution?

(b) What voltage must be applied to V_IN(–)?

(d) What voltage must be applied to V_REF/2?

(e) What binary value will represent 72°F?

(f) What is the resolution in °F? In volts?
