ABSTRACT:
An amplifier stage includes an operational amplifier having inverting and non-inverting inputs and an output and a resistive tee network coupled in the feedback loop between the inverting input and output to the non-inverting input which network is reference to the voltage applied at the non-inverting input for setting the gain of the amplifier stage. The amplifier stage may be combined with a differential pressure sensor for providing a single ended output voltage in response to the differential voltage outputs of the pressure sensor being applied to the inverting and non-inverting inputs of the amplifier stage.
