Microscope
Electromagnetic, electrostatic, and dynamic focus control are the most common deflection applications for Apex Microtechnology power operational amplifiers. These devices deliver exceptional combinations of high speed, high current and high voltage operation. A design rule of thumb for deflection circuits is to select an amplifier with a minimum slew rate equal to 10 times faster than the desired slew rate to ensure crisp settling performance. For electromagnetic deflection, a combination of high speed and high current is the optimal combination, along with an extended supply range, so the amplifier can slew the current in the yoke rapidly. High-voltage operational amplifiers are best suited to electrostatic deflection and/or focus. Apex Microtechnology products offer slew rate performance from a low of 100 V/µs to an industry first 3,000 V/µs for a single-package solution. Operating voltages range from 50 V to 450 V single supply, and output current capabilities range from .04 A to 15 A.

Ultrasonic Therapy and Surgical Tools
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.
