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, 11ohms versus 22ohms, 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.
