Instructions for Using NJM386D:

1. Power Supply:

   • The NJM386D can operate with a supply voltage ranging from 4.5V to 18V. Ensure the supply voltage is within this range to avoid damage to the IC.

2. Quiescent Current:

   • The quiescent current is typically 3.5mA at a supply voltage of 12V. This value should be considered when designing the power supply circuit to ensure efficient power usage.

3. Output Power:

   • The typical output power is 70mW into an 8Ω load with a total harmonic distortion (THD) of 1%. This makes it suitable for low-power audio applications.

4. Total Harmonic Distortion:

   • The THD is typically 0.1% at 70mW output power and 1kHz frequency. This indicates good sound quality and minimal distortion.

5. Signal-to-Noise Ratio:

   • The signal-to-noise ratio (SNR) is typically 90dB, which ensures a clean audio output with minimal noise.

6. Input Sensitivity:

   • The input sensitivity is typically 200mV for 70mW output power at 1kHz. This value helps in setting up the input signal level correctly.

7. Input Impedance:

   • The input impedance is typically 47kΩ, which is high enough to not significantly load the preceding stage.

8. Output Impedance:

   • The output impedance is typically 10Ω, which is low to drive most audio loads effectively.

9. Power Supply Rejection Ratio:

   • The power supply rejection ratio (PSRR) is typically 70dB at 1kHz, indicating good rejection of power supply noise.

10. Operating and Storage Temperature:

    • The operating temperature range is from -40°C to 85°C, and the storage temperature range is from -65°C to 150°C. Ensure the device operates within these temperature limits to prevent damage.

11. Circuit Design:

    • Use appropriate decoupling capacitors (e.g., 100nF and 10μF) close to the power supply pins to filter out noise and ensure stable operation.
    • Connect the output to the load through a coupling capacitor to block any DC component.
    • If using the NJM386D in a stereo configuration, ensure both channels have similar components to maintain balanced performance.

12. Handling:

    • Handle the IC with care to avoid static damage. Use proper ESD protection measures when handling and soldering the component.

By following these guidelines, you can ensure optimal performance and reliability of the NJM386D in your audio applications.
