(57) ABSTRACT A driver circuit for driving, for example, ultrasonic trans ducers in medical
equipment, such as ultrasound scanning equipment. The driver circuit includes first inputs
receptive of a pulsed signal, second inputs receptive of an analog signal, an output for
applying a pulsed drive signal or an analog drive signal to a load. A pair of output transistors
of complementary polarities are positioned with their current paths in series between
opposing supply lines with a con nection point intermediate between the transistors of the …
