Power amplifier PZD350A series

high-voltageDCfor piezo-electric actuators

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. Key Specifications Output Voltage Range Bipolar: 0 to ±350 V DC or peak AC Unipolar: 0 to +700 V DC or peak AC or 0 to -700 VDC or peak AC Output Current Range Bipolar: 0 to ±200 mA Unipolar: 0 to ±100 mA Slew Rate Bipolar: Greater than 550 V/μs Unipolar: Greater than 440 V μs Large Signal Bandwidth Bipolar: DC to greater than 250 kHz (-3 dB); DC to greater than 90 kHz (1% distortion) Unipolar: DC to greater than 200 kHz (-3 dB); DC to greater than 70 kHz (1% distortion) Small Signal Bandwidth Bipolar: DC to greater than 350 kHz (-3 dB) Unipolar: DC to greater than 250 kHz (-3 dB) DC Voltage Gain: 0 to 150 V/V, adjustable using a front panel potentiometer Typical Applications Include Piezoelectric driving/control Laser modulation MEMS Semiconductor research Piezoelectric vibration damping
