The FSxy bits allow selection of the DSD filter from three kind of filters for each channel. The x suffix in the register
name designates the channel, from 1 to 8, for which the filter is being selected. The y suffix in the register name
designates the high or low bit of the filter selection value.

ANALOG OUTPUTS
The DSD1608 includes eight independent output channels: V
OUT
1 to V
OUT
8. These are unbalanced outputs, each
capable of driving 4 Vp-p typical into a 10-k
ac-coupled load. The internal output amplifiers for V
OUT
1 to V
OUT
8 are
biased to the dc common-mode (or bipolar zero) voltage, equal to V
CC
/2.
The output amplifiers include an RC continuous-time filter, which helps to reduce the out-of-band noise energy
present at the DAC outputs due to the noise shaping characteristics of the DSD1608 delta-sigma D/A converters.
The frequency response of this filter is shown in Figure 30. By itself, this filter is not enough to attenuate the
out-of-band noise to an acceptable level for many applications. An external low-pass filter is required to provide
sufficient out-of-band noise rejection. Further discussion of DAC post-filter circuits is provided in the
Applications
Information
section of this data sheet.
