A small pressure transducer has the characteristics shown in given Figure.
Design an interface that will operate between 10 and 30 psi. An input of 10 psi should produce 0 V and 30 psi should produce + 5 V.
The transducer is modeled as a voltage source in series with a 500-Ω resistor that can vary ±75 Ω depending on the pressure. The OP AMPs you must use have a maximum closed-loop gain of 2000. Your only available bias source is the ±15VCC supply.
