A driver circuit for driving, for example, ultrasonic transducers 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 connection point intermediate between the transistors of the pair of transistors. The connection point between output transistors is coupled to the output of the circuit. The control terminals of the output transistors, which are coupled together, may be coupled to the first inputs with the driver functioning as a pulser, or else coupled to the second inputs with the driver functioning as a linear driver.
