Package The HV7322 device is an 8-channel, true 5-level or
pseudo 7-level, high-voltage pulser, with integrated T/R
switches. HV7322 is designed for medical ultrasound
applications. It is also fitted for NDT and other
transducer drive applications. Applications The integrated circuit (IC) has built-in gate-driver floating voltage regulators, allowing VPP0,1,2 and VNN0,1,2
high-voltage rails to move the voltage interdependently
from 0 to В±80V or to 60V. Each of the pulsers has output
voltage overshoot clamping diodes to the highest level
of the supply pin of VPP0 or VNN0 rails respectively. The
differential clock inputs take Differential Clock or …
