Instructions for AK5381ET
Power Supply Requirements:
- Ensure the supply voltage (VDD) is within the range of 2.7V to 3.6V.
- Use a stable power source to avoid noise and fluctuations.
Analog Input Connection:
- Connect the analog audio signal to the VIN pin ensuring it does not exceed the supply voltage VDD.
- For optimal performance, use a low-noise input signal.
Signal Processing:
- The device supports various sampling rates up to 192kHz. Choose the appropriate rate based on your application needs.
- Set the desired interface format (I2S, Left-justified) using configuration settings or external control pins as specified in the datasheet.
Power Management:
- Monitor power consumption which typically stays around 2.5mA in active mode.
- Consider power-saving modes if applicable for your application.
Performance Optimization:
- To achieve the best signal-to-noise ratio (SNR) of 95dB and minimize total harmonic distortion plus noise (THD+N) to 0.004%, ensure all connections are secure and free from interference.
Installation and Handling:
- Handle with care to prevent electrostatic discharge (ESD) damage.
- Follow the recommended layout guidelines provided in the datasheet for PCB design.
For detailed specifications and advanced configurations, refer to the official AKM Semiconductor datasheet for the AK5381ET.
