The MVUS01 ultrasound transducer interface is the first generation of high-voltage (HV) ultrasound ASICs intended for portable medical imaging probes and other markets. The chip supports pulsing ultrasonic transducers, with excitation voltages of up to 50V, and has high gain and low noise receivers, for
increased sensitivity to ultrasonic echoes. The chip is programmable to support a wide range of loads, at reasonable current consumption levels.
