STMicroelectronics provides a recommended PCB layout in the application note AN4841, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and thermal dissipation.
The STA120DJ is a highly configurable device, and the configuration depends on the specific audio application. STMicroelectronics provides a software development kit (SDK) that includes a configuration tool and example code to help engineers configure the device for their specific use case.
The STA120DJ is capable of delivering up to 120W of power per channel into a 4Ω load. However, the maximum power handling capability depends on the specific application, thermal management, and PCB design. Engineers should consult the datasheet and application notes for more information.
To ensure EMC, engineers should follow the guidelines provided in the application note AN4841, which includes recommendations for PCB layout, component selection, and shielding. Additionally, STMicroelectronics provides an EMC-compliant evaluation board that can be used as a reference design.
The STA120DJ has a thermal pad that must be connected to a heat sink or a thermal management system to ensure proper heat dissipation. Engineers should follow the thermal management guidelines provided in the datasheet and application notes to ensure reliable operation.
