The piezo driver and amplifier Trek® PZD350A is ideal for piezoelectric driving and control, laser modulation, microelectromechanical systems (MEMS), and numerous other applications. It’s configured as a non-inverting amplifier with a variable DC gain, but an inverting amplifier configuration is also available.

The Trek PZD350A amplifier features an all-solid-state design, high slew rates, and a four-quadrant active output. This output sinks or sources current into reactive or resistive loads throughout the output voltage range which is essential for achieving the accurate output responses and high slew rates demanded by reactive loads.


  • Control the gain, 0 to 150 V/V
  • Drive capacitive loads with four-quadrant output
  • Rely on ultra-accurate outputs thanks to low-output noise
  • Save costs thanks to maintenance-free operation and an all-solid-state design
  • Achieve high accuracy via a closed-loop system


  • Automatic power limit
  • Dynamic adjustment
  • Digitally enabled
  • NIST-traceable calibration certificate provided with each unit
  • DC-stable for programmable supply applications

Select specifications are shown below. Please see product data sheet for additional specifications.
