analog outputs
The PCM1606 includes six independent output channels, VOUT1 through VOUT6. These are unbalanced
outputs, each capable of driving 3.1 Vp-p typical into a 5-k
ac load with VCC = 5 V. The internal output amplifiers
for VOUT1 through VOUT6 are dc-biased to the common-mode (or bipolar zero) voltage, equal to VCC/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 PCM1606’s delta-sigma D/A
converters. The frequency response of this filter is shown in Figure 7. By itself, this filter is not enough to
attenuate the out-of-band noise to an acceptable level for most 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 Application Information section of this data sheet.
