Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (VDD) is within the specified range of 2.7V to 5.5V.
   • Use a stable power supply to avoid any noise or instability that could affect performance.

2. Digital Input:

   • The digital input voltage (VD) should be within the range of 1.8V to 5.5V.
   • Ensure the digital input signals are clean and free from excessive noise.

3. Output Configuration:

   • The differential output voltage (VOUT) typically ranges from 1.0Vpp to 3.0Vpp.
   • Connect the outputs to appropriate load impedances to ensure optimal performance.

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

   • The SNR is typically 110dB at 1kHz with A-weighting.
   • This value indicates the quality of the analog output signal relative to the background noise.

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

   • The THD+N is typically 0.0005% at 1kHz and -90dBFS.
   • This parameter measures the distortion and noise introduced by the DAC.

6. Dynamic Range:

   • The dynamic range is typically 110dB at 1kHz with A-weighting.
   • This indicates the range over which the DAC can operate without significant loss of signal quality.

7. Power Consumption:

   • The typical power consumption is 160mW at 5V and full scale.
   • Ensure adequate cooling if operating in high-temperature environments or with multiple devices.

8. Temperature Considerations:

   • The operating temperature range is -40°C to 85°C.
   • The storage temperature range is -65°C to 150°C.
   • Avoid exposing the device to temperatures outside these ranges to prevent damage.

9. Handling:

   • Handle the PCM1793DBR with care to avoid static discharge, which can damage the device.
   • Follow proper ESD (Electrostatic Discharge) precautions when handling and installing the component.

10. Layout and Grounding:

    • Use a well-designed PCB layout with proper grounding to minimize noise and interference.
    • Keep signal traces short and shield sensitive analog signals from digital noise sources.
