Integrated Analog Lowpass Filter
The DAC output of the sigma-delta modulator is fol-
lowed by an analog smoothing filter that attenuates
high-frequency quantization noise. The corner frequen-
cy of the filter is approximately 2 x fS.
Integrated Analog Output Buffer
Following the analog lowpass filter, the analog signal is
routed through internal buffers to OUTR and OUTL. The
buffer can directly drive load resistances larger than
3k
Ω and load capacitances up to 100pF (Figure 3).
