The architecture supports multiple output configurations including BTL, PBTL, and SE to provide design flexibility for different speaker loads.
Applications
Key Specifications
Getting Started
For evaluation, utilize the TPA3255EVM to verify thermal performance and audio metrics. Designers should pay close attention to the 44-HTSSOP thermal pad soldering and ensure low-ESR decoupling capacitors are placed close to the PVDD pins. Configuration of the device is handled through hardware pins, while fault monitoring can be integrated into a system MCU via the fault and reset pins.
