Chapter 1. Product Overview
1.1 INTRODUCTION
The HV2722 Analog Switch Evaluation Board (ADM00946) works with the HV MUX
Controller Board (ADM00825) to provide No High-Voltage Bias, 32-Channel,
High-Voltage Analog Switches with L-Switch Architecture demonstration, including
basic on/off switch operation, and 2:1 MUX operation with two built-in MD1822,
TP2640 and TN2640 pulser circuits.
1.2 HV2722 DEVICE SHORT OVERVIEW
The HV2722 device is a 300V, low-charge injection, 16-channel high-voltage analog
switch. It is designed to be used in applications requiring high-voltage switching,
controlled by low-voltage command signals, such as medical ultrasound imaging,
driving piezoelectric transducers and in printers. Using the 300V high-voltage CMOS
technology, the typical 18

on-resistance analog switch can pass the analog pulse
signal up to ±3A and ±135V, under high-voltage supplies of ±150V. It requires 3.3V or
5V for the logic operation.
