Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage is within the range of 4.5V to 5.5V.
   • Connect the positive terminal of the power supply to Vcc and the negative terminal to GND.

2. Standby Mode:

   • To put the device into standby mode, apply a low signal to the STBY pin. The standby current will be approximately 10 渭A.
   • To activate the device, apply a high signal to the STBY pin.

3. Input Signal:

   • Connect the input signal to the IN+ and IN- pins.
   • The input sensitivity should be between 100 mV and 300 mV for optimal performance.
   • The input impedance is 47 k惟.

4. Output Configuration:

   • Connect the speaker to the OUT+ and OUT- pins.
   • The device can drive an 8惟 speaker with a typical output power of 1.2W.

5. Thermal Management:

   • Ensure adequate heat dissipation if the device is operated at high power levels or in high ambient temperatures.
   • The operating temperature range is from -20掳C to 85掳C.

6. Storage:

   • Store the device in a dry place with temperatures ranging from -40掳C to 125掳C.

7. Signal-to-Noise Ratio:

   • The device has a typical SNR of 75 dB, ensuring a clean audio output.

8. Total Harmonic Distortion:

   • The THD is typically 0.5%, providing high-quality audio reproduction.

9. Handling:

   • Handle the device with care to avoid damage to the pins and internal components.
   • Use appropriate ESD protection when handling the device to prevent static damage.
