Eight Channel Programmable

High Voltage Ultrasound Transmit Beamformer

Features

General Description

► Eight channels with return to zero

► Up to ±70V output voltage

► ±3.0A output current

The Supertex HV7351 is an 8-channel programmable high

voltage ultrasound transmit beamformer. Each channel is

capable of swinging up to ±70V with an active discharge back

to 0V. The outputs can source and sink more than 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.

► Store up to four different patterns

► Independent programmable delays

► Single 11x11 QFN-80 package

Application

Each pulser has four associated 64-bit shift registers for

storing pre-determined 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 200MHz,

allowing incremental delays down to 5ns.

► Medical ultrasound imaging

► NDT, non-destructive testing

► Arbitrary pattern generator

► High speed PIN diode driver
