Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (VCC) is within the range of 4.5V to 16V.
   • Connect the power supply to the VCC pin and ground to the GND pin.

2. Input Connection:

   • Connect the audio input signal to the IN pin.
   • The input impedance is 10kΩ, so ensure the source impedance is compatible to avoid loading issues.

3. Output Connection:

   • Connect the load (e.g., speaker) to the OUT pin.
   • The output can swing from 1.3V to 3.7V when VCC is 5V and the load resistance is 600Ω.

4. Quiescent Current:

   • The quiescent current is typically 0.8mA at 5V supply. This should be considered in power budget calculations.

5. Signal-to-Noise Ratio:

   • The device has a high SNR of 90dB, which ensures minimal background noise.

6. Total Harmonic Distortion:

   • At 1kHz and 1Vrms output, the THD+N is 0.003%, indicating excellent linearity and low distortion.

7. Input Sensitivity:

   • The input sensitivity is between 0.7V and 1.5V for a 1Vrms output at 1kHz.

8. Power Consumption:

   • The typical power consumption is 12mW under standard operating conditions.

9. Operating Temperature:

   • Ensure the operating temperature is within the specified range for reliable performance.

10. Layout Considerations:

    • Use short leads and proper grounding techniques to minimize noise and interference.
    • Place decoupling capacitors close to the VCC and GND pins to stabilize the power supply.

11. Storage and Handling:

    • Store the device in a dry environment and handle with care to avoid damage.
