AUDIO DACs
The ADAU1401 includes four Σ-Δ DACs. The SNR of the DAC
is 104 dB, and the THD + N is 90 dB. A full-scale output on
the DACs is 0.9 V
rms
(2.5 V p-p).
The DACs are in an inverting configuration. If a signal inversion
from input to output is undesirable, it can be reversed either by
using an inverting configuration for the output filter or by simply
inverting the signal in the SigmaDSP program flow.
The DAC outputs can be filtered with either an active or a
passive reconstruction filter. A single-pole, passive, low-pass
filter with a 50 kHz corner frequency, as shown in Figure 18, is
sufficient to filter the DAC out-of-band noise, although an
active filter may provide better audio performance.
Rev. 0 | Page 20 of 52
shows a triple-pole, active, low-pass filter that provides a steeper
roll-off and better stop-band attenuation than the passive filter.
In this configuration, the V+ and V pins of the AD8606 op
amp are set to VDD and ground, respectively.
To properly initialize the DACs, Bits DS [1:0] in the DAC setup
register (Address 2087) should be set to 01.
