Instructions for Using LA4422

1. Power Supply:

   • Connect the supply voltage (Vcc) to the Vcc pin and ground (GND) to the GND pin.
   • Ensure the supply voltage is within the range of 4.5V to 5.5V.

2. Input Connection:

   • Connect the audio input signal to the IN+ and IN- pins.
   • The input sensitivity should be between 100mV and 300mV for optimal performance.

3. Output Connection:

   • Connect the speaker or load to the OUT+ and OUT- pins.
   • Ensure the load resistance (RL) is 8Ω for stereo operation.

4. Shutdown Mode:

   • To put the device into shutdown mode, connect the SHUTDOWN pin to GND.
   • The shutdown current will be approximately 0.1μA.

5. Frequency Response:

   • The frequency response is flat from 20Hz to 20kHz at -3dB.

6. Thermal Management:

   • Ensure adequate heat dissipation if operating at high power levels to prevent overheating.

7. Signal-to-Noise Ratio:

   • The SNR is typically 70dB, with a range of 65dB to 75dB depending on conditions.

8. Total Harmonic Distortion:

   • The THD is typically 0.5% and should not exceed 1% under normal operating conditions.

9. Quiescent Current:

   • The quiescent current is typically 10mA when Vcc is 5V.

10. Storage and Handling:

    • Store the device in a dry, cool place to avoid damage.
    • Handle with care to prevent static discharge, which can damage the internal components.
