Apex推出多款功率放大器
(產品新聞, 2006年1月4日)
|
Apex Microtechnology has relesased power amplifiers. The PA78, PA86 and PA69 are high voltage ICs targeted at the growing use of piezo electric devices in industrial and medical markets. Piezos are hailed for their ability to generate fine movement in applications such as commercial ink jet printers and ultrasonic cleaners. This high speed trio provides customers with various combinations of standby current. The device is capable of achieving slew rates of up to 350V/盜 on supply voltages of 350V. The PA78 series also delivers up to 150mA of output current while generating very little standby current. - less than 1mA depending on performance requirements. The IC's design provides for high slew rates in pulse applications while maintaining very low quiescent current of under 1mA. Slew rate performance is independent of supply current while exhibiting a functional relationship to voltage amplitude. More simply stated, as the input signal increases, so does slew rate.
