Instructions for Use:

  1. Power Supply:

    • Ensure the supply voltage (VDD) is within the specified range of 2.7 V to 5.5 V.
    • Connect a decoupling capacitor (typically 0.1 μF) close to the power pins to stabilize the supply.
  2. Digital Inputs:

    • The digital inputs must be driven with differential signals.
    • Logic high levels should be at least 0.8 V, and logic low levels should be no more than 0.2 V.
  3. Output Configuration:

    • The PCM1716E/2K can drive a load directly or through an external buffer.
    • Do not exceed the maximum output current of 20 mA per channel.
  4. Signal Quality:

    • For optimal performance, ensure the signal-to-noise ratio (SNR) is maintained at 104 dB or better.
    • Keep the total harmonic distortion plus noise (THD+N) below 0.0009% for high-quality audio.
  5. Temperature Considerations:

    • Operate the device within the temperature range of -40°C to 85°C.
    • Store the device in an environment where temperatures do not exceed -65°C to 150°C.
  6. Power Consumption:

    • At 3.3 V and a sampling rate of 44.1 kHz, the typical power consumption is 15 mW.
  7. Layout and Grounding:

    • Use a ground plane to minimize noise and improve signal integrity.
    • Place the device as close as possible to other components in the signal path to reduce trace lengths.
  8. Initialization:

    • Refer to the datasheet for specific initialization sequences if required by your application.
  9. Handling:

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