Instructions for Use

1. Power Supply:

   • Connect the VDD pin to a stable power supply between 2.5V and 3.6V.
   • Ensure the power supply has sufficient decoupling capacitors (e.g., 10μF and 0.1μF) placed close to the VDD pin.

2. Digital I/O:

   • Connect the VDDIO pin to the appropriate I/O voltage (1.62V to 3.6V).
   • Configure the digital audio interface (I2S, TDM, PCM, or PDM) according to your application requirements.

3. Analog Inputs:

   • Connect differential line inputs to the INP1P, INP1N, INP2P, and INP2N pins.
   • Ensure input signals are within the specified sensitivity range (100mVrms).

4. Analog Outputs:

   • Connect differential line outputs from the OUT1P, OUT1N, OUT2P, and OUT2N pins to your audio output stage.
   • Ensure the output level is set appropriately (1.5Vrms).

5. Class D Amplifier:

   • Connect the speaker outputs (SPK1P, SPK1N, SPK2P, SPK2N) to the speakers.
   • Configure the amplifier settings (gain, volume, etc.) via the digital control interface.

6. Software Configuration:

   • Use the I2C or SPI interface to configure the codec settings.
   • Refer to the datasheet for register maps and configuration details.

7. Power Management:

   • Use the power-down mode to reduce power consumption when the device is not in use.
   • The standby current is approximately 1μA.

8. Thermal Considerations:

   • Ensure adequate heat dissipation for the Class D amplifier, especially at high output powers.
   • Place the device on a PCB with good thermal conductivity and consider using a heatsink if necessary.

9. Electromagnetic Interference (EMI):

   • Use proper PCB layout techniques to minimize EMI, such as short traces for high-frequency signals and ground planes.

10. Storage and Handling:

    • Store the device in a dry environment within the specified storage temperature range.
    • Handle with care to avoid damage from electrostatic discharge (ESD).
