Wideband Noise
The wideband noise of the lter is the total RMS value
of the device’s noise spectral density and determines the
operating signal-to-noise ratio. The frequency contents
of the wideband noise lie within the lter’s passband. The
wideband noise cannot be reduced by adding post ltering.
The total wideband noise is nearly independent of the
clock frequency and depends slightly on the power supply
voltage (see Table 3). The clock feedthrough specications
are not part of the wideband noise.

APPLICATIONS INFORMATION
Aliasing
Aliasing is an inherent phenomenon of sampled data
systems and occurs for input frequencies approaching
the sampling frequency. The internal sampling frequency
of the LTC1069-6 is 100 times its cutoff frequency. For
instance, if a 98.5kHz, 100mVRMS signal is applied at
the input of an LTC1069-6 operating with a 50kHz clock,
a 1.5kHz, 484μVRMS alias signal will appear at the lter
output. Table 4 shows details.
