Instructions for AK4385ET

1. Power Supply:

   • Ensure the supply voltage (VCC) is within the range of 2.7V to 5.5V.
   • Use a stable power source to avoid voltage fluctuations that can affect performance.

2. Standby Mode:

   • To enter standby mode, set the appropriate control pin to the specified level (usually low).
   • The typical current consumption in standby mode is 100 μA.

3. Operating Mode:

   • For normal operation, ensure the device is powered and the control pins are set correctly.
   • The typical operating current is 30 mA at 5V.

4. Signal-to-Noise Ratio (SNR):

   • The device provides a high SNR of 110 dB over the audio frequency range (20Hz to 20kHz).

5. Total Harmonic Distortion (THD+N):

   • At 1kHz and 0dBFS, the THD+N is typically 0.002%.

6. Output Voltage Swing:

   • The maximum output voltage swing is 2.0 Vpp into a 10kΩ load.

7. Input Sensitivity:

   • The input sensitivity is 0.2V for a 2Vrms, 1kHz signal.

8. Power Consumption:

   • The typical power consumption during operation is 150 mW at 5V.

9. Handling Precautions:

   • Handle the device with care to avoid static damage.
   • Follow proper soldering techniques to ensure reliable connections.

10. Layout Recommendations:

    • Place the device close to the power supply and ground planes to minimize noise.
    • Use bypass capacitors (typically 100nF and 10μF) near the power supply pins to filter out noise.

11. Storage:

    • Store the device in a dry, cool place to prevent moisture damage.
    • Follow the recommended storage conditions provided by the manufacturer.

For more detailed information, refer to the datasheet and application notes provided by the manufacturer.
