Abstract
A high voltage analog switch can be used in medical ultrasound applications. The high voltage analog switch can pass high voltage transducer excitation signals without necessarily having any high voltage power supplies. The high voltage analog switch can include three output switches, with one of the output switches having a clamp circuit for ensuring that transistors of an output switch on an input end of the high voltage analog switch remain OFF when the high voltage analog switch is OFF.
