SLASEG6B May 2018 – June 2020 TAS3251
Placing the bypass and decoupling capacitors close to supply pins is required for stability and best performance. This applies to DVDD, AVDD, CPVDD, and PVDD.
The small bypass capacitors on the PVDD lines of the TAS3251 must be placed as close to the PVDD pins as possible. Not only does placing these devices far away from the pins increase the electromagnetic interference in the system, but doing so can also negatively affect the reliability of the device. Placement of these components too far from the TAS3251 device can cause ringing on the output pins that can cause the voltage on the output pin to exceed the maximum allowable ratings shown in the Absolute Maximum Ratings table, damaging the device. For that reason, the capacitors on the PVDD net must be no further away from their associated PVDD pins than what is shown in the example layouts in the Layout Examples section
