Instructions

Power Supply:
- Connect the power supply to the VCC pin and ground to the GND pin.
- Ensure the power supply voltage is within the specified range (2.7 V to 5.25 V).
Analog Input:
- Connect the analog audio signals to the INP+ and INM+ pins for the left channel, and INP- and INM- pins for the right channel.
- For differential inputs, connect both INP and INM pins.
- For single-ended inputs, connect the signal to INP and ground to INM.
Digital Interface:
- Connect the digital output pins (BCK, LRCK, SDOUT) to your microcontroller or DSP.
- Configure the interface mode (I2S, Left-justified, Right-justified, DSP) via the MODE pins or software configuration.
Clock Input:
- Provide an external clock signal to the BCK pin. The clock frequency should be within the specified range (3.072 MHz to 24.576 MHz).
- Ensure the clock signal is stable and clean to avoid jitter.
Shutdown Mode:
- To enter shutdown mode, set the SHDN pin to high.
- In shutdown mode, the device consumes minimal power (1 μA).
Initialization:
- After powering up, initialize the device by configuring the necessary registers via the digital interface.
- Refer to the datasheet for specific register settings and initialization sequences.
Data Conversion:
- Once initialized, the ADC will start converting the analog input signals to digital data.
- Read the digital data from the SDOUT pin using the configured digital interface.
Testing:
- Test the device by inputting a known analog signal and verifying the digital output.
- Use an oscilloscope or logic analyzer to monitor the digital signals and ensure proper operation.
Handling:
- Handle the device with care to avoid static damage.
- Follow ESD (Electrostatic Discharge) precautions when handling and soldering the device.
