Apex Microtechnology PA441 & PA443 350V Low Noise Power Amplifiers
Apex Microtechnology PA441 and PA443 350V Low Noise Power Amplifiers provide next-generation performance based on the PA34X product family. These ICs have improved a specialty high voltage process to offer a 96% reduction in signal noise. These devices also have a 2x improvement in offset voltage. These amplifiers are ideal for driving high voltage, fine motion systems for piezo positioning applications. The PA441 and PA443 have a low noise rating of 12µV RMS at 20kHz bandwidth (Cc = 68pF). In offset voltage performance, 5mV at 25°C is typical, with just 20mV at the entire operating temperature range (-40°C to +125°C).
