Maxim Addresses High-Voltage Needs in Industrial Ultrasound Applications

By: Luigi Franchini

Abstract: Most ICs for ultrasound transmission available today are aimed to cover medical applications and do not necessarily fit the needs for industrial applications. Industrial applications such as nondestructive tests (NDTs), flow meters, and sonar often have different requirements for voltage capability, current capability, and frequency. Thanks to their great flexibility, Maxim's high-voltage (HV) products can be used in a broad range of applications. This article presents a variety of applications for the MAX4940 quad HV digital pulser and the MAX4968 HV multiplexer (mux).
