The MD2134DB2is to used to generate the ultrasound transmit beamformingwaveform with the Gaussian profile, and the adjustablefrequency, amplitude and phase angle. It also provides informationon how to design a user application circuit and PCBusing the MD2134 and DN2625 devices. The MD2134DB2 circuit uses two depletion-mode MOSFETsin the push-pull mode to drive the coupled inductor. The twodepletion-mode MOSFETs are packaged in a single 5x5mmDFN package. The sources of the MOSFETs are directlydriven by the MD2134’s two outputs, whose maximum peaksinking current is up to 3.0A. These current source outputsare controlled by the MD2134’s internal array-switch of thefast PAM current sources.
