Design of amplifiers. The voltage produced by a thermocouple varies between 0 and 100 mV for the span it senses. The output required for display Interfacing methods and circuits 751 is between 0 V and 5 V. An operational amplifier with an open-loop input impedance of 10 MW and an open-loop gain of 106 is used for amplification. Devise a circuit, including the required resistors, to produce the required output
