Instructions
Power Supply Connections:
- Connect AVDD to the analog supply voltage (2.7V to 3.6V).
- Connect IOVDD to the digital I/O supply voltage (1.65V to 3.6V).
- Ensure proper decoupling capacitors are placed close to the power pins.
Digital Input:
- Connect the digital audio data and control signals (e.g., BCLK, LRCLK, SDATA) to the appropriate pins.
- Configure the device using the I2C or SPI interface as required.
Analog Output:
- Connect the analog output pins (OUTL, OUTR) to the load resistors (e.g., 10kΩ).
- Ensure the output is properly terminated to avoid signal degradation.
Shutdown Mode:
- To enter shutdown mode, set the SHUTDOWN pin to a high level.
- The device will consume minimal current in this mode.
Thermal Considerations:
- Ensure adequate heat dissipation if operating at high power levels or in high ambient temperatures.
Layout Recommendations:
- Use a ground plane to minimize noise and improve signal integrity.
- Keep signal traces short and direct to reduce parasitic capacitance and inductance.
Storage and Handling:
- Store the device in a dry, cool environment.
- Handle with care to avoid static damage; use ESD protection where necessary.
