Signal Bandwidth, Transition Noise and Noise
Equivalent Input Bandwidth
The LTC2453 includes a sinc
1
type digital filter with the first
notch located at f
0
= 60Hz. As such, the 3dB input signal
bandwidth is 26.54Hz. The calculated LTC2453 input signal
attenuation vs frequency over a wide frequency range is
shown in Figure 12. The calculated LTC2453 input signal
attenuation vs frequency at low frequencies is shown in
Figure 13. The converter noise level is about 1.4μV
RMS
and can be modeled by a white noise source connected
at the input of a noise-free converter.
On a related note, the LTC2453 uses two separate A/D
converters to digitize the positive and negative inputs.
Each of these A/D converters has 1.4μV
RMS
transition
noise. If one of the input voltages is within this small
transition noise band, then the output will fluctuate one
bit, regardless of the value of the other input voltage. If
both of the input voltages are within their transition noise
bands, the output can fluctuate 2 bits.
For a simple system noise analysis, the V
IN
drive circuit can
be modeled as a single-pole equivalent circuit character-
ized by a pole location f
i
and a noise spectral density n
i
.
If the converter has an unlimited bandwidth, or at least a
bandwidth substantially larger than f
i
, then the total noise
contribution of the external drive circuit would be:
n
i
i
Then, the total system noise level can be estimated as
the square root of the sum of (V
n2
) and the square of the
LTC2453 noise floor (~1.4
μ
V
2
).
