Abstract
A configurable input amplifier for position-measuring devices includes at least one amplifier unit, which has a first input and a second input, as well as a first output and a second output, and may be operated in at least two different configurations. In a first configuration, a first operational amplifier is arranged between the first input and the first output and a second operational amplifier is arranged between the second input and the second output, the first and second operational amplifiers being connected as signal amplifiers. Therefore, output signals, which are proportional to the input signals applied to the inputs, are available at the outputs. In a second configuration, the first operational amplifier is connected as a differential amplifier. In this manner, an output signal proportional to the difference of the input signals applied to the inputs is available at the output.
