APPLICATION INFORMATION
THEORY OF OPERATION
The THS3001 is a high-speed, operational amplifier configured in a current-feedback architecture. The device is
built using a 30-V, dielectrically isolated, complementary bipolar process with NPN and PNP transistors
possessing f_Ts of several GHz. This configuration implements an exceptionally high-performance amplifier that
has a wide bandwidth, high slew rate, fast settling time, and low distortion. A simplified schematic is shown in
Figure 47.
