• Multiple functions: Output polarity switching, output range shift, output monitoring, external output on/off control, DC bias addition, and DC offset adjustment

Applications:

• Driving and evaluation of piezoelectric elements
• Test and evaluation of display devices
• Power amplifier for signal or pulse generators
• Measurement of magnetizing characteristics (B-H curves)
• Driving of elastic surface wave ultrasonic motors and comb tooth-shaped electrodes in the field of nanotechnology and MEMS
• High-frequency ripple tests of capacitors
• Development of ink jet application technology
• Characteristics tests for semiconductors such as diodes and SCRs
• Characteristic test for the devices such as relays and switches

The BA4825 is a  power amplifier that handles DC to 2 MHz.,  signals and output broadband, high speed, and high voltage (300 Vp-p max) bipolar (both positive and negative polarities) outputs. While ordinary DC power supplies only supply one-way currents, the BA4825 amplifier supplies (source) and absorbs (sink) currents, and handles positive and negative voltages as well, because it operates across all four quadrants.
