APPLICATION INFORMATION
recommended power-supply decoupling
The recommended power-supply decoupling for the TLV320AIC22 is shown in Figure 24. Both high-frequency
and bulk decoupling capacitors are suggested. The high-frequency capacitors should be X7R type capacitors
or better. A 1-
F ceramic capacitor should be used to decouple the digital power supply.
