Electromagnetic, electrostatic and dynamic focus control are the most common deflection applications for Cirrus Logic power operational amplifiers featuring the technology of Apex Precision Power®. 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. Cirrus Logic brand 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.
