Abstract: An improved transducer amplifier includes a first operational amplifier having low drift of its input offset voltage characteristic and having a first output of a transducer connected to its positive input and a second output of the transducer connected by means of an input resistor to its negative input. The gain of the first operational amplifier is set by a feedback resistor. A second operational amplifier having low current drain is connected as a voltage follower with its input connected to the first transducer output. A differential signal produced between the voltage follower output and the output of the first operational amplifier is applied to a conventional differential to single ended converter circuit with precisely matched input and feedback resistors to eliminate the common mode voltage component of the differential signal and to reference an amplified error signal component of the differential signal to ground.
