... MHz. This means new levels of perfor- mance for sampled data and imaging systems. All of this perfor- mance as well as load drive in excess are made possible by Analog Devices’ advanced Complementary Bipolar (CB) process. Another unique feature of this circuit is that the addition of a single capacitor, C tion due to the output stage ...
