A differential amplifier arrangement ( 53 ) comprising an input stage ( 1 ) and an output stage ( 2 ) is described. The input stage ( 1 ) comprises a differential amplifier ( 3, 4 ) to which an offset compensation stage ( 10 ) is connected, which comprises at least one controllable current source ( 11 ) and which controls a bias signal of the differential amplifier ( 3, 4 ). With the described differential amplifier arrangement, which can preferably be used as an instrumentation amplifier, very precise compensation of input offsets can be carried out.
