Instructions

1. 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).

2. 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.

3. 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.

4. 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.

5. Shutdown Mode:

   • To enter shutdown mode, set the SHDN pin to high.
   • In shutdown mode, the device consumes minimal power (1 μA).

6. 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.

7. 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.

8. 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.

9. Handling:

   • Handle the device with care to avoid static damage.
   • Follow ESD (Electrostatic Discharge) precautions when handling and soldering the device.
