An ultrasound device includes: a plurality of transducers constituting a two-dimensional (2D) probe a signal processor configured to generate non-inverted signals based on first signals received from first transducers of a first group from among the plurality of transducers and to generate inverted signals based on second signals received from second transducers of a second group from among the plurality of transducers a beamformer configured to generate a first summing signal corresponding to the non-inverted signals by performing beamforming on the non-inverted signals and to generate a second summing signal corresponding to the inverted signals by performing beamforming on the inverted signals and a differential amplifier configured to differentially amplify the first summing signal and the second summing signal.
