How to use the evaluation board for the STHV64SW high voltage switch matrix
Introduction
The STEVAL-IME015V1 evaluation board is based on the
STHV64SW
high voltage switch matrix, designed for ultrasound
imaging applications.
The system can switch 64 independent high voltage channels through switch input and output connections on standard
2.54 mm headers, as well as through digital I/O's. Each channel can be used as a switch for external transmitters or receivers,
or to directly drive transducers for low frequency applications.
A standard ultrasound probe connector can be soldered to the board to help evaluate the performance of the STHV64SW
device in your application.
