Instructions for Use:

1. Power Supply:

   • Connect the positive terminal of the power supply to the Vcc pin and the negative terminal to the GND pin.
   • Ensure the supply voltage is within the range of 4.5V to 18V.

2. Input Connection:

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

3. Output Connection:

   • Connect the speaker to the output pin (OUT).
   • For optimal performance, use an 8Ω speaker.

4. Quiescent Current:

   • The quiescent current is typically 10mA. Ensure your power supply can handle this current.

5. Thermal Management:

   • The operating temperature range is from -40°C to 85°C. Ensure proper heat dissipation if operating at high temperatures.

6. Signal-to-Noise Ratio:

   • The SNR is typically 75dB, providing a clean audio output with minimal noise.

7. Total Harmonic Distortion:

   • The THD is typically 0.1% and can go up to 10% at maximum output power. Adjust the input signal level to maintain low distortion.

8. Storage:

   • Store the UPA2003G in a dry environment within the temperature range of -65°C to 150°C.

9. Handling:

   • Handle the UPA2003G with care to avoid damage. Use appropriate ESD protection when handling the device.

10. Testing:

    • When testing the device, start with a low input signal and gradually increase to the desired level while monitoring the output and temperature.
