It is designed to drive two N and two P-channel high voltage DMOS FETs for medical ultrasound applications but may be used in any application that needs a high output current for a capacitive load. The input stage of the MD1812 is a high-speed level translator that is able to operate from logic input signals of 1.2 to 5.0 volt amplitude. An adaptive threshold circuit is used to set the level translator threshold to the average of the input logic 0 and logic 1 levels. The level translator uses a proprietary circuit, which provides DC coupling together with high-speed operation. The output stage of the MD1812 has separate power connections enabling the output signal L and H levels to be chosen independently from the driver supply voltages. As an example, the input logic levels may be 0V and 1.8V, the control logic may be powered by +5V and –5V, and the output L .
