TLV320AIC3262, can I tie SPK_V, SRVDD, SLVD to VBATT?

Other Parts Discussed in Thread: TLV320AIC3262

Hello,

For the SPK_V, SRVDD, SLVDD on the TLV320AIC3262, do these need to be tied to a regulated voltage, or can it be tied to VBATT? If I tie to VBATT ,do I expect the speaker to sound different for different battery voltages?

Thank you

    Hi Jamaal,

    It can be tied to the system battery provided that the voltage level is within the recommended operating conditions described in the datasheet for these pins. Power supply noise into the speaker outputs is a function of the device PSRR.

    The Class-D output is closed loop. The output should sound similar as long as the supply does not go below the maximum signal swing expected. Otherwise, you might experience some clipping if the supply goes too low.

    Regards,
