High-Voltage ``Video'' Amplifier for Driving Piezoelectric Transducers

An inexpensive wide-band amplifier suitable for driving many piezoelectric transducers encountered in underwater sound propagation studies and laser research is described. Small signal bandwidth is dc to 5 MHz, with large signal response determined by a slew rate limit of 800 V/??s, at maximum output voltage and current of 280 V peak-to-peak and 1 A.
