The DC-stable Trek® PZD700A is a high voltage piezo driver and amplifier that offers precise control of customer specified output voltages in bipolar or unipolar ranges. It achieves the accurate output responses and high slew rates demanded by reactive loads by utilizing a four-quadrant active output stage that sinks or sources current into reactive or resistive loads.

The Trek PZD700A is configured as a non-inverting amplifier. An inverting configuration is available. Both configurations are available as either single or dual-channel instruments. The Trek PZD700A is benchtop operable or mountable via a 19-in rack.


  • Adjust gain, 0 to 300 V/V
  • 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
  • Safeguard equipment with short-circuit protection


  • Digitally enabled
  • Automatic power limit
  • Dynamic adjustment optimizes the AC response for various load parameters
  • NIST-traceable calibration certificate provided with each unit
  • Four-quadrant output for driving capacitive loads

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