Instructions for Using the PCM1702

1. Power Supply:

   • Connect the power supply (VDD) to a stable 5V source.
   • Ensure the power supply is within the specified range of 4.5V to 5.5V.

2. Digital Input:

   • Connect the digital input signals (VIN) to the appropriate pins.
   • Ensure the input voltage levels are within the specified range of 0V to 3.6V.

3. Analog Output:

   • Connect the analog output (VOUT) to your audio amplifier or speaker.
   • The output voltage is typically 2.5Vpp with no load. Adjust the load as necessary for your application.

4. Signal-to-Noise Ratio (SNR):

   • The PCM1702 provides a high SNR of 108dB, which ensures clear and clean audio output.

5. Total Harmonic Distortion + Noise (THD+N):

   • The THD+N is -96dB at 1kHz and 0dBFS, indicating minimal distortion and noise.

6. Dynamic Range:

   • The dynamic range is 108dB, allowing for a wide range of audio signal levels.

7. Channel Separation:

   • The channel separation is 100dB at 1kHz, ensuring that left and right channels are well isolated.

8. Output Current:

   • The output current can be up to 20mA continuously, with a typical value of 10mA.

9. Power Consumption:

   • The power consumption is 120mW when all channels are active.

10. General Considerations:

    • Use appropriate decoupling capacitors near the power supply pins to ensure stability.
    • Ensure proper grounding to minimize noise and interference.
    • Follow the recommended layout guidelines provided in the datasheet for optimal performance.
