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
T
s 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 43.

noise calculations and noise figure
Noise can cause errors on very small signals. This is especially true when amplifying small signals. The noise
model for the THS403x, shown in Figure 44, includes all of the noise sources as follows:
e
n
= Amplifier internal voltage noise (nV/
√
Hz)
IN+ = Noninverting current noise (pA/
√
Hz)
IN– = Inverting current noise (pA/
√
Hz)
e
Rx
= Thermal voltage noise associated with each resistor (e
Rx
= 4 kTR
x
)
