🔧 Application Guidelines
Design Considerations
The AD1887 is a high-performance audio codec that requires careful design consideration to achieve optimal performance. The device should be powered from a clean, low-noise power supply, and the analog input and output signals should be properly filtered and buffered.
Installation Guidelines
The AD1887 is available in a 48-terminal LQFP package and should be mounted on a printed circuit board (PCB) with a suitable thermal interface material. The device should be soldered to the PCB using a reflow soldering process.
Operational Notes
The AD1887 is a sensitive device that requires careful handling and operation. The device should be operated within the specified temperature range and should not be exposed to excessive moisture or vibration.
