Question:

We have a thermocouple which has an analogue output voltage range from 0 to 10 mV and we want

to connect it to a PC. In order to achieve this we have an ADC with a maximum range from 0 to 5 V.

a. Based upon a non-inverting amplifier design an amplifier circuit that can match the

thermocouple to the ADC.

b. The amplifier available has a non-infinite open loop gain of 107, determine how many bits

can have so that this error will not affect the output.
