Digital Filter
The devices contain an on-chip digital lowpass filter
that processes the data stream from each modulator
and generates the high-resolution output data. The low-
pass filter frequency response is determined by the
programmable output data rate. At the nominal 16ksps
output data rate, the -3dB bandwidth of the filter is
3.4kHz. The passband flatness is better than ±0.1dB
from 0 to 1.74kHz. The notches are located at 5.75kHz
and 7.195kHz. These frequencies scale linearly with the
output data rate. See Figure 2 and Table 1 for the fre-
quency response at different data rates.
Since the transfer function of a digital filter is repeatable
and predictable, it is possible to correct for frequency-
dependent attenuation in downstream software. See
the
Compensating for the Rolloff of the Digital Filter in a
Typical FFT Analysis section. The transfer function is
defined by the following equation:
where:
Gain is the filter gain.
fAIN is the analog input frequency.
fSAMPLE is the programmed output data rate, nominally
16kHz.
fXINCLOCK is the clock frequency at XIN, nominally
24.576MHz.
FIR_Gain (fAIN) is the normalized gain of the FIR filter
with the following filter coefficients, as a function of the
analog input frequency fAIN. These coefficients are
applied at the output data rate:
