It is designed for use in medical ultrasound imaging. The HV732 HV732 has built-in damping for faster RTZ waveform capability and high voltage MOSFET gate-clamping function for quick ramping of the output voltage amplitude. The HV732 HV732 consists of a control logic circuit, level translators, MOSFET gate drive buffers, clamp circuits, and high current, high voltage MOSFETs as the ultrasound transmitter pulser output stage. In the output stage there are two pairs of MOSFETs. Each pair consists of a P-channel and an N-channel MOSFET. They are designed to have the same impedance, and can provide peak currents of over ±2 amps. The built-in MOSFET gate driver outputs swing 0 to 12V on PDR and NDR pins. The P-channel damp output swings 0 to ­5V on the DMPO pin. Features: 0 to +/-100V /-100V output voltage Better ultrasound image resolution +/-2A source and sink current Capable of driving large medical ultrasound probes Up to 40 MHz operating frequency Wider ultrasound penetration ranges Built-in damping Allows fast RTZ waveform capability Internal clamp circuit 041706 Benefits: Provides quick output amplitude ramping Supertex inc.
