This device consists of one precision high-voltage amplifier. The amplifier puts out a 20-times amplified input voltage. The amplifier is extremely low-noise and dc accurate. It can drive high capacitive loads without stability problems.

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

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