脉冲发生器IC

ST's Medical Ultrasound Imaging IC Solutions offer a complete range of integrated high-voltage transmitters from quad and octal, to the latest device, the state-of-the art STHV1600 ultrasound pulser IC.

It is the most integrated 16-ch ultrasound pulser IC embedding high-resolution beamforming for its 16 independent channels. The user can easily program a code excitation implementing high voltage sequence states and store the resulting pattern in the on-board RAM memory (65 kbits), supporting integration of Shear Wave elastography mode onto existing diagnostic ultrasound modalities.

The SPI control interface reduces the number of input signals and pins, to give the flexibility to manage digital inputs in CMOS or LVDS mode clocked up to 200MHz. Each channel can support up to five output levels (5-Level) and the output stages can provide up to ±2A peak output current (or ±4A, with 3-Level), independent from the high-voltage power-supply pins.

ST’s proprietary BCD6s-SOI and BCD8sSOI process technologies enable the combination of low-voltage CMOS logic, precise analog circuitry, and robust power stages on the same chip, offering unprecedented level of integration.

Typical applications:

• Medical ultrasound imaging
• Point-of-care ultrasound imaging
• Non-destructive testing equipment
• Pulse waveform generator
• Sonar and radar systems
• Other piezoelectric, capacitive or MEMS transducers
