Amplifier HV-AMP200N-1

Precise Amplifier ±200 V

Jump to: Technical Data Download Additional Information

This plug-in module contains one precision high-voltage amplifier. The amplifier outputs a 20× amplification of the input voltage. The amplifier is extremely low-noise and DC accurate. It can drive high capacitive loads without any stability problems.

The DC accuracy and the extremely low noise predestine the module for the amplification of output signals of precise D/A converters. The high signal-to-noise ratio of about 125 dB can only be fully utilized with converters with a resolution of more than 20 bit.

Typical Applications: Control of piezoelectric elements for nano-positioning, control of electrostatic lenses and deflection systems
