  • Forum Post: How can AIC26 be configured to drive a mono differential signal between the HPR and HPL outputs?

    Ron6621
    The AIC26 audio output drivers in high power mode can be configured to drive a mono differential signal into a speaker load of 8-ohm minimum. The speaker load should be connected differentially between the HPR and HPL outputs. Several options are possible for playback of DAC data in this case. If a...

    Do you have the register dump for the device ? --> You might want to check if the master clock is being fed to the device. All clocks will originate from the master clock. --> Please check out the section 5.7 of the application reference guide http://www.ti.com/lit/ug/slau303/slau303.pdf...
