APPLICATION INFORMATION

theory of operation

The THS4001 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

fTs of several GHz. This results in 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 19.
