	Available for capacitive and inductive loads If a load containing a capacitor or coil is driven with alternating current, the current generally flows back from the load. In this case, an ordinary power supply or amplifier may not be able to drive the load. BA series amplifier also operates (i.e., outputs the current) with a capacitive or inductive load such as a piezoelectric element or solenoid. This is because it operates also with a sink, where the voltage and current directions are reverse.
	Broadband, high speed, and high-voltage BA4850 faithfully reproduces pulse signals with quick rise and complex waveform signals as well, because the frequency band is DC to 50 MHz and the slew rate is 6,000 V/µ s. BA4825 drives current from a large piezoelectric element or display device, because the band is DC to 2 MHz and the maximum high-voltage output is 300 Vp-p. Because both can amplify DC, they can be input waveforms containing an offset or those that are asymmetric in the positive area and negative area.
	Low output impedance BA series keep a low output impedance throughout the overall range (0.5Ω + 1.5 MHz or less typ. for BA4825). With the voltage drop (raised due to load connection) suppressed to the minimum, the power of the equipment is maximized.

	Driving and evaluation of piezoelectric elements
	High voltage and high speed are required when a piezoelectric element used for a piezoelectric inverter or piezoelectric actuator is to be driven and evaluated. In addition to high-voltage output, BA Series amplifiers keep extremely small output impedance. Therefore, they can offer superior step response against piezoelectric with large capacitance piezoelectric element.

	Test and evaluation of display devices
	Flat display panels such as FEDs and LCDs require high voltage for driving, and quick rise for evaluation of their response characteristics. With their high-voltage output and high slew rate, BA series amplifiers enable accurate drive tests and evaluations.

	Power amplifier for signal or pulse generators
	During evaluation process of power devices, the performance is evaluated with a broadband, high voltage, and large current. With their broadband, high speed, and high voltage output, BA series amplifiers evaluate and test devices, using various waveforms, pulse patterns, and arbitrary waveforms.

	Measurement of magnetizing characteristics (B-H curves)
	BA series can be used for magnetization measurement such as ferrite and or amorphous materials. Since the BA Series features the high frequency of 50 MHz required for measuring B-H curves, as well as high voltage output and high stability against inductive loads, you can reproduce stable measurement.
