The T750 is a compact 4-channel high-voltage pulse driver. Each channel includes an input comparator and a transformer-coupled high-voltage power output stage. Output pulses follow the logic inputs and are processed by an adaptive pulse width limiter that prevents output transformer saturation.
Highland Technology also offers the T760, a dual-channel compact high-voltage driver with fiberoptic inputs.
