Useful in piezoelectrics, electro-optics, and MEMS applications, the Trek Model PZD350A high-voltage power amplifier provides a large-signal bandwidth of 250 kHz (-3dB) and a small-signal bandwidth greater than 350 kHz (-3dB). Features include a DC accuracy of better than 0.1% of full scale and a slew rate greater than 500 V/µs (+/-350 V range) or 350 V/µs (700 V range). The protected four-quadrant, class AB, all-solid-state output stages prevent incidental short circuits, arcing, or energy return from the load device.
