APPLICATIONS INFORMATION
noise contribution of the external drive circuit would be
Vn = ni √π/2 Fi. Then, the total system noise level can
be estimated as the square root of the sum of (Vn2) and
the square of the LTC2450-1 noise oor (≈2
μV2).
Aliasing
The LTC2450-1 signal acquisition circuit is a sampled
data system and as such suffers from input signal alias-
ing. As can be seen from Figure 19, due to the very high
over-sample ratios the high frequency input signal attenu-
ation is reasonably good. Nevertheless a continuous time
antialiasing lter connected at the input will preserve
the converter accuracy when the input signal includes
undesirable high frequency components. The antialias-
ing function can be accomplished using the RS and CIN
components shown in Figure 15 sized such that
τ = RS
CIN > 450ns.

Bandwidth
The LTC2450-1 includes a sinc1 type digital lter with the
rst notch located at f0 = 60Hz. As such the 3dB input
signal bandwidth is 26.54Hz. The calculated LTC2450-1
input signal attenuation with frequency at low frequencies
is shown in Figure 18.
The LTC2450-1 input signal attenuation with frequency
over a wide frequency range is shown in Figure 19.
The converter noise level is about 1.4μVRMS and can be
modeled by a white noise source connected at the input
of a noise free converter.
For a simple system noise analysis the VIN drive circuit can
be modeled as a single pole equivalent circuit character-
ized by a pole location Fi and a noise spectral density ni.
If the converter has an unlimited bandwidth or at least
a bandwidth substantially larger than Fi, then the total
