В® Applications в–єв–є Medical ultrasound imaging
в–єв–є Non-destructive evaluation General Description The Supertex HV219 is a low switch resistance, low charge
injection, 8-channel, 200V, analog switch integrated circuit (IC)
intended primarily for medical ultrasound imaging. The device can
also be used for NDE (non-destructive evaluation) applications. The
HV219 is a lower switch resistance, 11О© versus 22О©, version of the
Supertex HV20220 device. The lower switch resistance will help
reduce insertion loss. It has the same pin configuration as that of the
Supertex HV20220PJ and the HV20220FG.
The device is manufactured using Supertex’s HVCMOSВ® (high …
