    ►► 25MHz ultrasound maximum frequency
    ►► PWM modulation push-pull current source
    ►► Focusing phase adjustment & chirp waveform
    ►► Fast SPI interface
    ►► 2.5V CMOS logic interface
    ►► +5.0V single power supply
    ►► Low second order harmonic distortions The MD2131 is a high-speed, arbitrary waveform, push-pull
    source driver. It is designed for medical ultrasound imaging and
    HIFU beamforming applications. It also can be used in NDT,
    Sonar and other ultrasound phase-array focusing beamforming
    The MD2131 consists of CMOS digital logic input circuits, an
    8-bit current DAC for waveform amplitude control, and four PWM
    current-sources. These current sources are constructed with the ...
