The Trek Model PZD350A is a high-voltage DC-stable piezo driver/amplifier designed to provide precise control of output voltages in bipolar or unipolar ranges that are customer specified within a range of available settings. It is configured as a noninverting amplifier with a variable DC gain. An inverting amplifier configuration is also available.
The unit features an all-solid-state design, a high slew rate and a four-quadrant active output stage which sinks or sources current into reactive or resistive loads throughout the output voltage range. This capability is essential for achieving the accurate output responses and high slew rates demanded by reactive loads.
Features and Benefits
