OUT3/OUT4 MIXERS AND OUTPUT STAGES
Figure 29 OUT3 and OUT4 Mixers
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 29.
The OUT3 and OUT4 output stages are powered from AVDD1 and AGND1.
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.
