9 Power Supply Recommendations

The TLV320AIC3110 has been designed to be extremely tolerant of power supply sequencing. However, in some rare cases, unexpected conditions and behaviors can be attributed to power supply sequencing.

It is important to consider that the digital activity must be separated from the analog and speaker activity. In order to separate the power supplies, the recommended power sequence is:

  1. Speaker supplies
  2. Digital supplies
  3. Analog supplies

First, turn on the speaker supplies. Once they are stabilized, turn on the digital power supplies. Finally, once the digital power supplies are stabilized, the analog power supplies must be turned on.

Also, TI recommends to add decoupling capacitors close to the power supplies pins (see Section 10 for details). These capacitors will ensure that the power pins will be stable. Additionally, undesired effects such pops will be avoided.
