OUT3/OUT4 MIXERS AND OUTPUT STAGES
The OUT3/OUT4 pins provide an additional stereo line output, a mono output, or a differential output.
There is a dedicated analogue mixer for OUT3 and one for OUT4 as shown in Figure 25.
The OUT3 and OUT4 output stages are powered from AVDD1 and AGND1.
Figure 25 OUT3 and OUT4 Mixers
OUT3 can provide a left line output, or a mono mix line output.
OUT4 can provide a right line output, or a mono mix line output.
A 6dB attenuation function is provided for OUT4, to prevent clipping during mixing of left and right
signals. This function is enabled by the OUT4ATTN register bit.
