Thermometer Design Problem
 There is a need to design a thermometer that can read from 30°C to 300°C to monitor the temperature of an Unmanned Aerial Vehicle's (UAV) power supply. The output will feed a 0-V to 5-V ADC prior to transmission of the temperature data to the ground. A reading of 30°C will deliver 0 V to the ADC, while 300°C will deliver 5 V.

Select an appropriate thermocouple with sufficient voltage spread from given Figure and design the instrumentation amplifier. Other criteria are as follows: the transducers have a 15-Ω series resistance; the fewer OP AMPs the better; since power is limited, the maximum OP AMP gain is 1000; and the bias voltage, if needed, must be from the available 15-V supply.
