Figure 3. Differential and Stereo Single-Ended Input Configurations
The MAX97000 features independent mixers for the left
headphone, right headphone, and speaker paths. Each
output can select any combination of any inputs. This
allows for mixing two audio signals together and rout-
ing independent signals to the headphone and speaker
amplifiers. If one of the inputs is not selected by either
mixer, it is automatically powered down to save power.
