MD2131DB1 - Ultrasound Beamforming Transmitter Demo Board (MD2131DB1)The MD2131DB1is to used to generate the ultrasound transmit beamformingwaveform with the Gaussian profile, and the adjustable frequency,amplitude and phase angle. The MD2131DB1 circuit uses two depletion-mode MOSFETsin the push-pull mode to drive the center tapped, wide band,ultrasound output transformer. The two depletion-modeMOSFETs are packaged in a single 5x5mm DFN package.The sources of the MOSFETs are directly driven by theMD2131’s two outputs, whose maximum peak sinking currentis up to 3.0A. These current source outputs are controlled bythe MD2131’s internal angular vector switch matrix and thein-phase and quadrature PWM input signals.
