OUTPUT SIGNAL PATH

The outputs HPOUTL and LINEOUTL are derived from the Left DAC output, whilst the outputs

HPOUTR and LINEOUTR are derived from the Right DAC output, as illustrated in Figure 22.

A feedback path for common mode noise rejection is provided at HPOUTFB and LINEOUTFB for the

Headphone and Line outputs respectively. This pin must be connected to ground for normal

operation.

Each analogue output can be separately enabled; independent volume control is also provided for

each output. The signal paths and associated control registers are illustrated in Figure 22.
