Overview
HV7360/HV7361 High-Speed ±100V 2.
5A Two-or-Three-Level Ultrasound Pulsers Features • High-Density Integration AC-coupled Pulser • 0V to ±100V Output Voltage • ±2.
5A Source and Sink Minimum Pulse Current • Up to 35 MHz Operating Frequency • 2 ns Matched Delay Times • 2.
5V, 3.
3V or 5V CMOS Logic Interface • Built-in Two-terminal Low-noise Interface for HV7361 • Low Power Consumption and No Floating Power Supply Rails or Decoupling Capacitors Applications • Medical Ultrasound Imaging • Piezoelectric Transducer Drivers • Ultrasound Industrial NDT • Pulse Waveform Generator General Description The HV7360/HV7361 are high-voltage and high-speed pulse generators with built-in, fast return-to-zero damping Field-Effect Transistors (FETs).
An added feature to HV7361 is an integrated two-terminal low-noise T/R switch.
These integrated circuits are designed not only for portable medical ultrasound image devices but also for NDT and test equipment applications.
Both the HV7360/HV7361 are composed of controller logic interface circuits, level translators and AC-coupled Metal Oxide Semiconductor Field-Effect Transistor (MOSFET) gate drivers.
They also have high-voltage and high-current P-channel and N-channel MOSFETs as output stages.
The peak output currents of each channel are guaranteed to be over ±2.
5A with up to ±100V of pulse swing.
The AC coupling topology for the gate drivers not only saves two floating voltage supplies but also makes the PCB layout easier.
Package Type 22-lead CABGA (Top view) See Table 2-1 for pad information.
