HV7351
8-Channel, В±70V, 3A Programmable High-Voltage
Ultrasound-Transmit Beamformer
Features General Description The HV7351 device is an 8-channel programmable
high-voltage ultrasound-transmit beamformer. Each
channel is capable of swinging up to В±70V with an
active discharge back to 0V. The outputs can source
and sink up to 3.0A to achieve fast output rise and fall
times. The active discharge is also capable of sourcing
and sinking 3.0A for a fast return to ground. The topology of the HV7351 will significantly reduce the number
of I/O logic control lines needed. Eight Channels with Return-to-Zero (RTZ)
Up to В±70V Output Voltage
В±3.0A Output Current
Stores up to Four Different Patterns
Independent Programmable Delays
80-lead Single 11 x 11 mm VQFN Package Applications Each pulser has four associated 64-bit shift registers
for storing predetermined transmit patterns and a 10-bit
delay counter for controlling the transmit time. One of
four arbitrary patterns can be transmitted with adjustable delay, depending on the data loaded into these
shift registers and the delay counter. The delay counter
can be clocked up to 200 MHz, allowing incremental
delays down to 5 ns. Medical Ultrasound Imaging
