PA443DF - Apex Microtechnology

Description: Representing a fourth product iteration, the PA44X series provides next generation performance based on the PA34X product family (no longer supported for design in). These new IC designs leverage improvements in a specialty high voltage process to provide a staggering 96 percent reduction in signal noise and an equally impressive 2X improvement on offset voltage. For piezo positioning applications, a low noise rating of 12µV RMS at 20kHz bandwidth (Cc = 68pF) makes the PA441DF/PA441DW/PA443DF the amplifiers
