STHV748SQ

Quad ±90 V, ±2 A, 3/5 level, ESD-enhanced high-speed ultrasound pulser

ECCN USEAR99
ECCN EUNEC
Packing TypeTray
RoHs compliantEcopack3
GradeIndustrial
Package NameVFQFPN 64 9x9x1.0 mm

This monolithic, high-voltage, high-speed pulser generator features four independent channels. It is designed for medical ultrasound imaging applications, but can also be used to drive piezoelectric, capacitive or MEMS based transducers.The STHV748S is composed of a controller logic interface...
