APPLICATION INFORMATION
theory of operation
The THS405x 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 42.

noise calculations and noise figure
Noise can cause errors on very small signals. This is especially true when amplifying small signals, where
signal-to-noise ratio (SNR) is very important. The noise model for the THS405x is shown in Figure 43. This
model 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
)
