The Apex Microtechnology product family of high-voltage and high-speed linear power amplifier are the solutions of choice for piezoelectric driver applications for more than 25 years. These off-the-shelf, single package ICs, hybrids and board-level modules are commonly used to deliver very high voltages which drive the fine movement of piezoelectric elements. To expand the range of applications bridge configurations can increase total piezo drive voltage, and composite configuration with other small signal amplifiers offers flexibility to improve overall system precision.
