APPLICATION INFORMATION
THEORY OF OPERATION
The THS403x is a high-speed operational amplifier configured in a voltage feedback architecture. It is built using
a 30-V, dielectrically isolated, complementary bipolar process with NPN and PNP transistors possessing f_Ts of
several GHz. This results in an exceptionally high-performance amplifier that has wide bandwidth, high slew rate,
fast settling time, and low distortion. A simplified schematic is shown in Figure 51.
