MD2134DB1 - Beamforming Transmitter Demo Board (MD2134DB1)
The MD2134DB1 is usedto generate the ultrasound transmit beam formingwaveform with the Gaussian profile, and the adjustable frequency,amplitude and phase angle. It also provides informationabout how to design a user application circuit and PCBusing the MD2134K7 and DN2625DK6 devices. The MD2134DB1 circuit uses a pair of depletion mode, highvoltage, DN2625 MOSFETs in the push-pull mode to drivethe center-tap wide band ultrasound output transformer. The MOSFETs are in one 8-Lead DFN surface mount package. The sources of the MOSFETs are directly driven by the MD2134’s two outputs, whose maximum peak sinking current is up to 3.3A. These current-source outputs are controlled bythe MD1234’s internal current source switch array and the inputsignals M[3:0].
