Model PZD700A M/S Piezo Driver/Amplifier

Trek’s PZD700A M/S Piezo Driver/Amplifier system provides precise voltage control and delivers twice the current of our standard Model PZD700A. This high-voltage DC powered amplifier has an available bipolar voltage range of 0 to ±700 V and unipolar ranges of 0 to +1400 V or 0 to -1400 V DC peak AC.

Its output current ratings are ±200 mA for the bipolar range and ±100 mA for the unipolar ranges. Voltage ranges are customer specified and factory set. The PZD700AM/S signal input is configured as a noninverting amplifier. An inverting amplifier configuration is also available.

Applications for the Model PZD700A M/S include piezoelectric driving/control, laser modulation, MEMS, semiconductor research, and piezoelectric vibration damping. Features include an all-solid-state design, impressive slew rates of “greater than” 380 V/μs for the bipolar model and 370 V/μs for the unipolar models, and superior bandwidth capabilities with “DC to greater than” large signal bandwidth (-3 dB) of 150 kHz for the bipolar model, 125 kHz for the unipolar models, and small signal bandwidth (-3 dB) of 200 kHz (all models).

A four-quadrant active output stage sinks or sources current into reactive or resistive loads throughout the output voltage range. This is essential to achieve the accurate output responses and high slew rates demanded by reactive loads.

Precision voltage and current monitors provide buffered low voltage representations of the high-voltage output and load current for monitoring purposes or for use as feedback signals in a closed-loop system. The Digital Enable feature provides a connection for a remote device to turn ON and OFF the high voltage of the instrument. A DC voltage gain adjustment allows the output to be adjusted from 0 to 300 V/V.

The PZD700A M/S has a Dynamics Adjustment feature that is used to optimize the AC response of the output signal under various load configurations. It is bench top operable or with optional equipment, in a standard 19-inch rack.

Trek Model PZD700A (with 1/2 the current capability) is available in single channel or dual channel instruments and can be operated on a bench top or, with optional hardware, in a standard 19-inch rack. (To PZD700A web page...)
