The A400DI is a dual general purpose broadband linear amplifier having a fixed amplification of 20 times and capable of bipolar high voltage output of ±200V.
Any function generator or arbitrary waveform generator or any other signal source with amplitude up to ±10 V can be used as an input device.

The amplifier’s output is linear from DC up to megahertz range.

It can be used in a wide range of applications, for example to drive piezo actuators, MEMS, OLEDs, liquid crystals, etc.

It features also a low voltage phase inverter that inverts the signal applied to the input of channel 1. The resulting signal can then be connected to the input of channel 2 by means of a short BNC cable (supplied). As a result the two outputs operate in counter-phase. Connecting a load between the outputs effectively doubles the amplitude range. Please note that the load cannot have any connection to ground.
