Line-Level Outputs and Filtering
The CODEC contains on-chip buffer amplifiers capable of producing line level single-ended outputs on
AOUTA and AOUTB. These amplifiers are ground centered and do not have any DC offset. A load stabi-
Connection Diagram (Hardware Mode)” on page 11, is required on the analog outputs. This allows the
DAC amplifiers to drive line or headphone outputs.
Also shown in the Typical Connection diagrams is the recommended passive output filter to support high-
er impedances such as those found on the inputs to operational amplifiers. “Rext”, shown in the typical
connection diagrams, is the input impedance of the receiving device.
The invert and digital gain controls may be used to provide phase and/or amplitude compensation for an
external filter.
The delta-sigma conversion process produces high frequency noise beyond the audio passband, most of
which is removed by the on-chip analog filters. The remaining out-of-band noise can be attenuated using
an off-chip low pass filter.
